Questions related to Insect Diversity
as an educator in conservation, it is very important that i teach methods that are non destructive. such as counting insect visitation to flowers, for pollinator diversity and abundance studies. i have found only one reference (Frankie et al. 2005) suggesting an appropriate time to observe flowers. thanks in advance
I recent completed a study looking at insect diversity in a metal polluted landscape using pit traps. I am interested in specifically focusing on predatory insects and want to adjust my methods to collect primarily spiders and beetles. Does anyone have any suggestions that might allow me to collect large amounts of predators?
A friend is sending me 15 Blattidae sp. "African Bullet" roaches so that I can formally ID them and publish the species description in a scientific paper. The roaches originate from a domestic colony- founding members were collected from a log at the base of Mt. Kilimanjaro. This species has been commonly misidentified as Bantua robusta.
This is my first time writing a species description paper. Does anyone have links to existing papers that would make good examples/templates for my paper? Or advice that I could use when going about this project?
I have the details about exactly how I will perform my dissections more or less straightened out. What I am less familiar with is the process of writing the paper, and exactly what information is usually included in these papers.
Unfortunately I am in a situation where I do not have the strength to leave my house due to an infection with a serious case of late-stage Lyme disease + co-infections. I figured this might be an important factor to mention.
I am hoping to write this paper as a sort of "screw you" to my disease, and so I can continue to make progress even while I cannot attend college. Any help that anyone could offer would be incredibly valuable, and I thank you in advance!
We aim to capture nocturnal flying insects (which can be potential prey for bats) and, therefore, we are going to use UV light traps.
We will sample three different habitats in Colombia: preserved savannas, riparian forest, and rice crops. Our idea is to sample the open area (savanna, rice fields) at the same time as the forest, and we are contemplating installing two light traps in each one of these habitats, with a separation of c. 100 m.
Is it appropriate to use two traps per habitat to get a good idea of insect diversity?
the objectives of insect sampling in forest is to determine the abundance, diversity and habitat association of insect in forest ecosystem
A lot of studies, reviewers or scientists consider that fine investigations account a high number of data collection site (>15) sufficiently spaced at human scale to represent actual insect diversity. But what is the actual spatial scale of insect communtiy structure ? This should be more challenged in current studies. Maybe observationnal sites with 200 m will harbor different insect communities ? I started this point of debate cause I know that it will be some divergent opinions according to the selected insect taxonomic group and also the researcher feeling.
We found a Long-eared Owl breeding in a rock face in eastern Switzerland. I never heard about such a nest site from Central Europe. But there are observations of such a behaviour from Kazakhstan (Karyakin et al. 2007), Mallorca (König, pers. comm.) and Canary islands (Scott 1997). Does anybody know further cases of Long-eared Owls breeding in rock faces?
For insect diversity comparisons, I plan to capture, count and identify all insects found/trapped. I haven't started with the counts yet, but are currently exploring the possibilities. I have read much about all different techniques to measure, compare, extrapolate, rarefy etc to analyse the data - which is great! The only problem is that I'll try to identify all individuals to species level, but probably won't be able to (therefore assigned it as precise as possible, for example to genus). As far as I know, all the methods (like Shannon entropy, Chao, Simpsons, Richness etc) are based on the fact that all the individuals are based on the same taxonomic level, right? Am I obligated to "downgrade" all my identification data to the lowest taxa available (for example pool all species to their associated genus level)? Or is it also possible to analyse diversity with OTU's of different levels? Thanks in advance!
We are conducting a study on mangrove insect diversity. We want to know the specific kind of bait depending on the diet of the insect. If they are carnivorous, or if they are attracted to sugar solutions, what can we use for bait? Thank you!
Despite of its economic importance little seems to be known about the development of the frequency of Hylotrupes bajulus (European House borer, house longhorn beetle, old house borer). In the fantastic study of Lindhe et al. (2010) evidence for a dramatic decline of the beetle in the last 100 years in Sweden was presented. A questionnaire returned by 104 experts allows the estimation of a similar decline in Germany (to be published 2016 or 2017). Does anybody know of data or estimates for other countries? Even a simple statement of your personal estimation of the development of Hylotrupes in your own country would be helpful. Thank you
Lindhe, A.; Jeppsson, T.; Ehnström, B. (2010): Longhorn beetles in Sweden - changes in distribution and abundance over the last two hundred years. Entomologisk Tidskrift 2010 Vol. 131 No. 4 pp. 241-508. ISSN 0013-886X .
A recent analysis made on Cerambycids sold by a local seller as collected in "Saraburi" during the late 80s years revealed that they are all Malayan or even Bornean species.
Moreover, the collection dates correspond to a season where no insect can be found on flowers in southern Thailand.
The "impossibility" to find such species in Saraburi is confirmed by the fact that Chrysomelidae collected in Saraburi in the 50s years (Kimoto & Gressitt, 1979; 1981) does not include Bornean species, but only Indo-Chinese ones.
This problem concerns many species recorded as new for Thailand and even new species, whose original locality is "Saraburi".
The same problem can also concern all other group of insects subject to commercial trade, with patent biogeographic and/or taxonomic dramatic consequences..
Do you have further informations?
I am looking for a source of Carnation tortrix moth (eggs or larvae) to start a culture of my own.
I am trying to find a taxonomic key or paper highlighting the key distinguishing characteristics of the predatory mites Amblyseius swirskii and Neoseiulus californicus. I would ideally like to be able to distinguish them while looking at a sample of both mites. Any suggestions would be appreciated.
In my research activities on Phillip Island off Norfolk, South Pacific, I have recorded an example of cross-fostering with a species of Pterodroma incubating and rearing an Ardenna (Puffinus) species. This nest was followed (several visits then surveillance camera) from incubation until the near-fledged chick left the nest area following abandonment of breeding pair. I am seeking examples of other burrowing species doing the same. If unpublished material of similar extent, I and my co-authors are happy to work towards a joint note in an ornithological publication.
I collected many sample of scolytid which intercepted from the imported tropical Africa log, but I cannot identify some of them besides of Xyleborus sp. Some samples belong to the Hylesinini tribe is most difficult to identify.
It looks like Anopheles Arabiensis. But smaller and has white colour fungus like growths in the body (abdomen). They are bigger than the local mosquitoes. The habitat is a paddy field in a dry zone of Sri Lanka. But found them in the rainy season.
I need information about Chinavia musiva (Hemiptera: Pentatomidae), like biology, hosts and importance for crops. Thanks
As more and more amateur ornithology projects are including population genetics, or, institutions rely on amateur bird ringers/ornithologists to collect samples, I though it might be useful to have specimen storage clarified.
So, given what is available to those of us who don't have access to a lab supplies, how is it best to store biological specimens collected in the field and what makes a good preservative?
There are stories of vodka and orange juice being used where ethanol isn't available...
This moth was pictured some days ago resting on the lowest branches of an old spruce in a mountain area in northern part of Norway. The camouflage on its back was absolutely perfect compared to the lichen growing on the stem and branches. Does anyone have a suggestion for a name?
I found bark beetle, probably Hypothenemus eruditus Westwood, 1836 (Curculionidae: Scolytinae), but I can't find any identification key to confirm it.
If anyone has it I will be grateful for sharing.
Recent news is worrying. Caterpillars of the wax moth Galleria mellonella digest artificial plastics (Bombelli et al 2017) and it has been suggested that they might be produced en masse to help consume the vast amounts of waste plastic that have accumulated worldwide. One can imagine that releasing large numbers of the caterpillars could pose a serious problem for honeybee colonies.
Does anybody has experience with measuring the wing length of large living beetles? Of course without damaging them so they can be released and followed up?
I am currently planning a study on identifying the prey of a recently discovered Hydraena species in the Philippines using DNA-based methods. I have been looking for references on the diet of water beetles in general and on more specific taxa that Hydraena is a part, to no avail. Most studies I have found were descriptions of the morphology and habitat of water beetles. What could be the possible diet of a Hydraena species located in Southeast Asia?
Stephanopachys species are illusive with only few recent records known from Latvia. In order to clarify distribution pattern of these protected beetles, an innovative and highly efficient attracting / collecting methodology to be used.
I am looking for publications or raw data on attractant pheromones for Stephanopachys species. Any help or experience from the international scientific community is greatly appreciated.
1. Take the picture of an insect from the ARP system;
2. Compare this picture with those in a image database;
3. Provide relevant results if the image is similar to some insect images;
4. Collect GPS data while confirm some interesting insect groups;
5. Automatic raise the question on the taxonomy informations if the previous image was possibly wrongly identified.
6. Share the image with taxonomy if the author would like to do it for other public media.
I wrote a blog in Chinese asking the same question below -
I have attached some photos of a single fly. Please tell me the species of this fly. I shall be highly obliged.
I NEED ASSISTANCE ON THE VARIOUS LAND SPECULATION THEORIES AND INDICES
I am a research student at the UNIVERSITY OF LAGOS, NIGERIA. I am currently carrying a research on land speculation and control in Nigeria but got stalked as i could not lay my hands on any likely theories on land speculation and measuring indices. I hereby seek your assistance on any available theories as well as articles that could be of help.
Thank you greatly,
Need to confirm identification of the larvae in the soil (eastern china agricultural landscape). Adult trap data suggest a mix of two species (H. parallela and A. corpulenta) but need to confirm on laval populations. Cannot find any good key on the larvae.
An image from Java (Serang: Bulakan: Rawa lake National Park, 120-340m asl. 13.III.2011. author: Guido Bohne) found in Flickr shows a 'squid pygmy grasshopper' (Phaesticus mellerborgi, family Tetrigidae) standing on a leaf and having parasitoid hymenopteran (family Eulophidae, ID provided by @Doug Yanega) on its discus of the pronotum.
First of all, I would like to know if anybody is has any information on identity of this tiny wasp (grasshopper is 10-14 mm in length without antennae). If not, I would lke to know if experts think that the tiny wasp is P. mellerborgi specific parasitoid?
Secondly, I would like to get any information on parasitoids of Tetrigidae, published and observed.
Some further information: Phaesticus mellerborgi is species living in peninsular Malaysia, Sumatra, and Java (on Borneo there is P. insularis). Species incuded in this genus have nymphs that are squid-like in appearance, with coloration. The species live in wet habitats , on the ground, eating detritus algae and mosses.
We are looking for an entomologist / taxonomist who is willing to identify this Venturia species (Hymenoptera: Ichneumonidae) that we encounter in the Bolivian Altiplano.
This Venturia is an endemic parasitoid of Eurysacca quinoae (Gelechiidae). Eurysacca larvae cause damage in quinoa crop cultivation.
Since PROINPA is a Bolivian NGO, we are not able to pay you for this job. But of course the scientific credits for discovering a new species are yours!
(Dead samples send upon request)
I'm searching for someone who can get some material of adults Microdon myrmicae and/or Microdon mutabilis of diverse localities in Europe (dryed or into alcohol) for my personal research project. Other species of Microdon are also interesting for this project. I have many difficulties to find these species on the field.
Thanks in advance !
I need the images of male genitals or morphological characters of Aphrophora exoleta for identification
My student have completed one paper on Myiopardalis pardalina in Chinese. We decided to publish it in Chinese journal.
Where can we find photos on this pest(adult, larval, egg, and so on) and damage in fields
In China, we have not found this pest.
I like to publish it with you if you like
This stick-insect is from the place near Matucana in Peru, this is middle of western slope of Andes (with aride climate), altitude about 2400 m. a.s.l. These insects keep themselves on ground, can be found under stones.
By using Shanon-Wiener Diversity Index, how do we explain insect diversity based on the calculated value? Is it the higher the value, that means the arthropod community in the plot is diverse?
I am looking for a good ID key for nymphs of North American Pentatomidae. I found great keys for adults and even eggs, but nothing really satisfying regarding nymphal instars. Could you suggest good papers and/or websites or attach any related key to your answer?
I really appreciate any help you can provide!
Insect classification of A. D. Imms / Gullan and Cranston or any other? Some classify insects into 29 orders, some into 30 orders some 33 orders, some excludes protura, diplura and collembola.
Is it possible for Bactrocera dorsalis and Ceratitis species to mate; if it is possible can introgression occur between Bactrocera dorsalis and Ceratitis species ?
I am collaborating with Masahiko Tanahashi on a comparative study of their mycangium xylose-fermenting yeasts. Presently, we need specimens across their range; except for the UK and Switzerland. Specimens from Spain are top priority; this is to solve the riddle of the origin of the famous Pichia stipitis yeast CBS 6054. For more see: The mystery of the lesser stag beetle Dorcus parallelipipedus (L.) (Coleoptera: Lucanidae) mycangium yeasts. Bulletin of the Amateur Entomologists' Society, 72 (510): 146-152.
Recently I have been interested in Gnathotrichus materiarius (Fitch, 1858). It is an invasive species from North America, which for the first time was found in Europe in 1933 (France). I found some publications, but information about biology and ecology of this species are modest and inadequate.
In libraries I have an access I found only these publications:

If someone has an access to any other publications about this bark beetle, I will be grateful if you let me know
Thanking you in advance for any help.
I have an estimate of 1.5 million cicadas per acre (3.7 million per ha) by Dybas and Davis (1962, Ecology 43:432-444). This is the most commonly cited density estimate for cicadas in the popular media.
I have estimates ranging from 6.9 million per ha to 60 million per ha for monarch butterflies overwintering in Mexico. Citations are Calvert, W.H. 2004. Two methods estimating overwintering monarch population size in Mexico. The Monarch Butterfly: Biology and Conservation (ed. by Oberhauser, K.S., & Solensky, M.J.), pp. 121–127.

I have roughly 600,000 grasshoppers per ha, which appears to be outbreak levels reported by Kemp and Davis (1993: Oecologia 96:1-8).
I found that Australian plague locusts can reach 2 million per ha, though I don't have a good source for it. Zha et al. (2008: Photogr Eng & RS 74:619-624) indicated Oriental migratory locusts could reach 60 million per ha density.
Unfortunately, I'm having a difficult time finding published estimates of density for insect species; I simply do not know the literature well enough. Can anyone point me to credible sources describing the densities of a wide array of insect species? Are there reviews in the entomological literature on this topic?
Can I use the abdomen to differentiate B. dorsalis from B. kandiensis and B. invadens syn dorsalis? Can someone provide me with some clear images of these fruit flies?
From this National Nature Park I got several perfect photos of aposematic and camouflage signs of insects and some of them are identified due to help of specialists over RG site. So, due to yours kind help I moved with my manual-book in Biotsenology enough good.
Shown mantis photo was made in top afternoon when no any shadows, so possibly one of 30 photos is useful...
Can we make it by own? please suggest
I have to check the butterfly diversity in a particular area. So I have to use bait traps for the collection of butterflies. I have a little bit idea of this trap. Can anybody suggest me to how to use this? Could it be possible to make it own? please suggest. Thank you.
