Longhorn Beetle - Science topic

I'm so grateful Mikhail F. Bagaturov

You might want to check the following webpage for the Curculionidae of Brasil, http://www.coleoptera-neotropical.org/paginas/2_PAISES/Brasil/Curculionoidea/curcul_bras.html,. It will get you started.

Hello Huseyin; Let me comment only on the youngest fossils. The processes of fossilization are so incremental that I wouldn't be able to find a border. Let's take as an example the creatures caught in asphalt seeps. The La Brea Tar Pits in Los Angeles, California may be the best known. Some of the beetles are found inside the skulls of large, extinct mammals while others are still struggling on the sticky surface of the flow. Some of the oldest Tenebrionid specimens are evidently members of extant species wandering around in the nearby foothills.

So, defining the youngest ones will prove to be pretty tricky. Cheers, Jim Des Lauriers

For coleoptera: Pimelia, Scarabaeus, Anthia, ... Some species can also change the period of activity depending on the season (especially in deserts like Anthia sexmaculata)

You might also look into predatory flies like the Asilidae. They are known to perch near flowers and target anthophilous visitors. I have not seen many in the field with known flower-visiting cerambycid prey, but that is anecdotal.

Dear Denis Demidko just in case that this question is still of interest to you: You can see Psacothea hilaris flying away when you watch the following YouTube video entitled

Here in C. Greece, although I search every summer quite a lot for saproxylic beetles in big, old coniferous forests (Mt. Ossa, Pindos Mts., Olympos Mt.,..) with many dead trees, I have encountered only very few specimens of Hylotrupes bajulus over the years (all females) there. Always, only single specimens encountered, and never found it to be common. It worths to mention that, in buildings, I only found it once in my life recently (1 female specimen) in the suburbs of Larisa city.

Alcohol should be avoided for killing beetles, as it makes them stiff as hell, and then very hard to spread the legs. It also makes them brittle quite quickly (a few days in alcohol are enough for this to happen), and often oily, too, as it dissolves the fat. If the beetle is oily, one or more gazoline baths will remove oil and recover the original color.

First one is Prosopocera undulata.

ethanol will evaporate more quickly.

At least some radiator coolant is toxic. Animals like drinking it, but die. One purpose of the dye is to mark radiator fluid as toxic, otherwise it looks like water.

Sticky traps will require frequent replacement because the trap will become full and the trapped insects will attract ants and animals. Handling the sticky material can be unpleasant and makes everything sticky.

Water has the advantage that it is non-toxic and cleaning up is easy. You could try adding something like calcium chloride. This salt is deliquescent and will prevent the trap from drying out completely if the humidity is high. I am not sure what concentration would be ideal. Another option would be to place a tank of water above the trap and have the water slowly drip into the trap to replace water lost by evaporation.

I guess you can read about speculation motive of holding money, then speculation as an investment strategy in economics too

Hello Kulanthaivel:

Before sequences can be uploaded to BOLD, specimen data records must be uploaded to a BOLD project. Sequences can be uploaded directly to BOLD for loci that have been registered in the BOLD’s marker database. New marker loci can be registered by emailing support@boldsystems.org with a description of the loci and an example GenBank accession. Upon upload of sequences, BOLD automatically compares the COI sequences against known contaminants (Human, Mouse, Cow, Pig, Wolbachia, etc.) and flags the record if there is a reasonable match. The upload event (person, activity, and timestamp) and the institution supporting the sequence editing are recorded in the audit trail to ensure proper attribution.

Check out the protocol and procedure in the Bold System web page

This species is increasingly rare in Luxembourg as well, though small series of 4-5 specimens wee found in Elsaß and Saarland until a few time ago. I could only collect single specimens, only 3 times in different localities, in 7 years of field research throughout the country.

You can identify this species as Gnoma sticticollis Thomson, 1857.

Dillon & Dillon (1951) described two further species from Java (and synonymised some other ones preserved in Paris), without, nonetheless, seeing Paris' types.

According to Breuning, who worked in Paris, these species were valid.

As usual, the papers of these American entomologists are very questionable.

hello Tadeusz . You can contact any rearing insect center e.g  http://www.irc.entomology.msstate.edu/

Burrowing beetles that have tibia 'teeth' with which they dig show greater wear of the teeth the older they are.

Dear Davood, thank you for your reply. Many of the Australian Lucanidae were described in the 19th and early 20th century. The descriptions are often based on one single specimen. There is a need to re-describe many and this most probably will lead to reviewing whole genera (e.g. Lissotes, Figulus). In order to achieve this, I would like to carry out DNA examinations and compare results to clarify identity of spp. and explore relations (or the lack of it) between  them. My e-mail follows. Best regards, George

Thanks a lot, Ramsi Mansour.

Your answer is very useful to the students and a designer who has a couple of these insects for drawing. As you might know, or not, I'm retired and have received that request from a colleague.

Kind regards,
