I just love chironomid pupal exuviae! So much fun to find new species to add to the Faroese checklist.

𝘋𝘪𝘢𝘮𝘦𝘴𝘢 𝘮𝘦𝘯𝘥𝘰𝘵𝘢𝘦 is a #non-bitingmidge (Diptera: #Chironomidae) found in glacial & high Arctic environments. Larvae survive entrapment in ice by entering diapause & producing antifreeze proteins & polyols to prevent ice crystal formation inside the cells #fly #scientificdrawing #insect

These aquatic insect larvae appeared in my freshwater aquarium left outside in Uppsala, Sweden. I suspect they are #Chironomidae #larvae, anyone can confirm?

You won't see a map like this very often on iNaturalist! the only record of 𝘗𝘳𝘰𝘥𝘪𝘢𝘮𝘦𝘴𝘢 𝘰𝘭𝘪𝘷𝘢𝘤𝘦𝘢 (with its characteristic moustache) in the whole of the UK! non-biting midges (Chironomidae) are extremely underrecorded at species level! #taxonomy #chironomidae #biodiversity

grey laboratory table, with small grey microscope, with camera, connected to a laptop via cable, there are also boxes with microscopy slides on the table
Screen showing automatic detection of the microfossils on the slide´s background
Subfossil midge of Genus Psectrocladius (2 specimens) on the microscopy slide. Yellow headcapsule with brown mouthparts. Specimens from Azores, portugal.
This #Fossilfriday🦴🦖 we got new system for semiautomatic scanning of the whole microscopic slides. Given how we are normally photographing thousands microfossils (mostly #Chironomidae head capsules) per year, it will save us ton of time and will contribute to machine learning application in Palaeo

We choose the worst possible day to start #fieldwork for lake #monitoring - cold wind, sleet, snow and rain... but nevertheless plenty of #Chironomidae pupal exuviae around!

Found this interesting midge and I’ve been trying to identify it but can’t put my finger on what species it is! I think it’s definitely a male non-biting midge, possibly Chironomus plumosus? Hard to tell without looking under a microscope! Any thoughts? 🪰 #Chironomidae #midge @flygirlnhm.bsky.social

This is 𝘗𝘢𝘳𝘢𝘮𝘦𝘳𝘪𝘯𝘢 sp. (genitalia, tibial spur, last antennal segment) from the Okavango Delta (Botswana). I'm working on several publications about different life stages of non-biting midges in this area #diptera #chironomidae #taxonomy

Figure 1 in Manfrin et al. (2025): "Study area in the Westhavelland Nature Park (Germany). a Depiction of the lit site (60 × 48 m, including the ditch) with 12 street lamps, 4 emergence traps and 12 air-eclector traps (not drawn to scale). Each emergence trap was adjacent to a street lamp. b Plan of experimental sites showing location of lit (Lit) and dark (Control) sites. The dark site was located along the same agricultural drainage ditch as the lit site, and had the same structural design, but lamps were not equipped with functioning bulbs. c Plan view depicting lamps as filled circles and emergence traps as triangles. The shaded (blue) rectangle delineates the water surface (300 m2) adjacent to each site. Map data (b) are by Google Earth Pro 7.3.0.3832 (32-bit) (5 Mar 5 2011), Lochow, Germany (52°41′29.81″ N, 12°27′37.54″ E; eye altitude 1.09 km; DigitalGlobe 2017)."

1st record in the south of England since the 1970s! 𝘗𝘢𝘳𝘢𝘵𝘢𝘯𝘺𝘵𝘢𝘳𝘴𝘶𝘴 𝘥𝘪𝘴𝘴𝘪𝘮𝘪𝘭𝘪𝘴. Very similar to 𝘙𝘩𝘦𝘰𝘵𝘢𝘯𝘺𝘵𝘢𝘳𝘴𝘶𝘴. Differences: pecten epipharyngis with 5 teeth, premandibles with wider inner tooth, mentum with dark median tooth, no fine striae on VPs #macroinvertebrates #chironomidae #taxonomy 🧪🌍

A picture of the mentum of Brillia longifurca (Diptera, Chironomidae) highlighting the outer teeth, long and well separated
This is the larva of 𝘉𝘳𝘪𝘭𝘭𝘪𝘢 𝘭𝘰𝘯𝘨𝘪𝘧𝘶𝘳𝘤𝘢 Kieffer (Diptera: Chironomidae) from the River Ash. The postmentum is the same colour as the rest of the head capsule & the outer laterals are long & well separated. This last feature isn't described in the guide by Cranston (1982) #chironomidae #entomology 🧪🌍

A desert robber #fly caught a #midge & rested patiently while I took MANY pics. Always a neat scene, though I wouldn't want to be that prey getting venom pumped into my neck and digested 😬

Our initial Hong Kong #Chironomidae survey is done. Elaine is busy making sure we get the traps down before Christmas. Over 200 new additions to the species checklist so far from the sample sorting. #biodiversity

A large non-biting midge #Chironomidae from the garden. Possibly Chironomus riparius or C. piger which I don't think can be separated morphologically
