The paper contributes to the knowledge of the robber fly fauna in the vicinity of Pleszew (Wielkopolsko-Kujawska Lowland, Poland). Research conducted between 2007 and 2024 resulted in the identification of a total of 34 species of Asilidae, including Pogonosoma minor Loew, 1869, which was recorded for the first time in Poland.

Materials for the knowledge of six families of flies (Diptera: Asilidae, Bombyliidae, During summer observations in the Powidzki Landscape Park in the years 2009-2024, 65 species from six families of flies were found. The most interesting species was Stratiomys singularior (Stratiomyidae), present on the list of endangered species in Poland, classi...

The hoverfly fauna of Poland is relatively well-known. After World War II and the loss of important natural history collections, large-scale efforts were initiated aimed at their comprehensive rebuild. These activities were conducted from the 1950s onward by researchers from the Polish Academy of Sciences and focused on the most valuable natural ar...

The 15th Dipterological Conference and the XLI Meeting of the Dipterological Section of the Polish Entomological Society was held on April 21st-23rd 2023 in Słopnice, in the Beskid Wyspowy (Island Beskids) in the Polish Carpathians. During this meeting, participants collected or photographed 76 species of flies, identified within 30 families. Among...

During numerous entomological surveys in the years 2006-2023 in Pleszew district (Wielkopolsko-Kujawska Lowland), flies from four families: Conopidae, Stratiomyidae, Syrphidae and Xylomyidae were collected and photographed. The material consists of approximately 1,800 individuals and is kept in the authors’ collections. It includes 11 species of th...

Using two cities, Rimini (Italy, Cfa climate) and Krakow (Poland, Cfb), as living laboratories, this research aimed at measuring in situ the capacity of 15 woody species to assimilate, sequester, and store CO2.

The paper provides information on the second record of the Carpomya (Goniglossum) wiedemanni Meigen, 1826 in Poland. The new site from the Wielkopolska-Kujawy Lowland in Central Poland shifts the known range of this species to the north.

The aim of the present study was to determine the fluctuating asymmetry of the first pair of wings in females Polistes nimpha (Christ, 1791) living in an environment contaminated with heavy metals. The average concentration of Zn, Cd and Pb in the bodies of the insects varied depending on the distance from the source of contamination, reaching the...

The aim of the research was to study the diversity of hoverflies (Syrphidae: Diptera) living in areas under the influence of heavy metal emissions (Cd, Zn and Pb). Although the area of the Olkusz Ore-bearing Region (OOR), where the research was partially conducted, belongs to the contaminated regions, where a relatively high species richness of Syr...

This paper summarises distribution in Poland and provides notes on the biology of three species of the subgenus Pollinocheila Barkalov, 2002 of the genus Cheilosia Meigen, 1822, whose larvae specialize in leaf mining. Alpine species Cheilosia rhodiolae Schmid, 2000 is provided for the first time from Poland and Central Europe based on specimens col...

1. Burrows are specific structures created by animals, characterised by specific conditions different from those in the surrounding environment. Therefore, burrows may play a role for many other animals than their owners. To test this view, we have chosen the burrows of red foxes Vulpes vulpes and badgers Meles meles, two main burrow dwellers from...

This report is the main outcome of Task 2.1 of work package 2 (WP2). Overall, this WP aims to analyze and compare the implementation of UF-NBS in selected cities and city regions in view of their impacts on urban ecosystems and societies, their cost effectiveness, and their replicability in distinct contents. In this context, Task 2.1 consisted of...

As a result of the revision of almost 1300 specimens of saproxylic hoverflies of the genera Brachyopa and Hammershmidtia from museum and private collections, the presence of 11 species of Brachyopa and one species of Hammerschmidtia was confirmed in Poland. The authors present rich material collected by entomologists from all over the country and p...

Pollinator foraging behavior plays a key role in breeding and therefore affects the evolution of the orchid reproductive strategy. Food-deceptive orchids usually implement a generalized plant pollination strategy and a relatively diverse group of pollinators visit them. Dactylorhiza majalis is a food-deceptive, early-flowering orchid that relies on...

The increased introduction of non-native species to habitats is a characteristic of globalisation. The impact of invading species on communities may be either linearly or non-linearly related to the invaders’ abundance in a habitat. However, non-linear relationships with a threshold point at which the community can no longer tolerate the invasive s...

Geographical distribution of the rare hoverfly, Eristalis anthophorina (FALLÉN, 1817), so far known from historical or unspecified data from Poland, is presented and discussed on the basis of new records.

The paper presents new records of flies from the family Mythicomyiidae in Poland as well as in Bulgaria, Ukraine (the Crimea) and Iran.

Loss of suitable seminatural habitats and homogenization of crop types have led to the population decline of pollinating insects in farmland. As these insects support crop production, many practical efforts aim to sustain pollinator diversity which is especially challenging in intensively managed and homogeneous farmland. However, there are ongoing...

Sphegina montana BECKER, 1921 was not listed from Poland since XIX century. Among the newly recorded species are also those that are considered rare in their range: Cheilosia nebulo...

A faunistic survey on the hoverflies of the Wigry National Park was conducted during the 7th Dipterological Workshop (June 13-18, 2017). In total 121 species of Syrphidae were found. The list of hoverfly species recorded during Workshop was compared with result obtained in previous year. 35 species of Syrphidae were new for Wigry National Park incl...

Automated species identification is a promising new method of solving the problem of identification of insects. However, in most previous studies based on this method, the number of identified species was relatively low. In this study, we tested the possibility of the identification of more than 200 species of Syrphidae. The identification was base...

A faunistic survey of hoverflies was conducted in the Wigry National Park during the 6th Dipterological Workshop (May 21-27, 2016) of the Polish Entomological Society. In total 132 species of Syrphidae were found. A small population of the species Sphecomyia vespiformis (GORSKI, 1852) was rediscovered.

Eristalis pertinax varies seasonally, with the spring morph more hairy than the summer morph. We measured the size and the venation of the wings of the seasonal morphs. Wings of the spring morph were significantly larger than those of the summer morph and those of females were larger than those of males. There were also significant differences betw...

Temnostoma angustistriatum KRIVOSHEINA, 2002 was recorded from Poland and Central Europe for the first time based on specimens from Bieszczady Mts, Lower Beskid and Białowieża Forest. The records from Poland are at the SW edge of the distribution of this species. New localities of T. angustistriatum and T. bombylans from Poland are listed.

Pollinating insect populations, essential for maintaining wild plant diversity and agricultural productivity, rely on (semi)natural habitats. An increasing human population is encroaching upon and deteriorating pollinator habitats. Thus the population persistence of pollinating insects and their associated ecosystem services may depend upon on man-...
