It’s an excellent feeling to identify flies

Muscidae aren’t my group so the @ukmuscidae.bsky.social @dipteristsforum.bsky.social workshop is brilliant for me

Using both @entmikeashworth.bsky.social and James McGills new keys, this is Polietes hirticus - a northern spp (this one from Cumbria)

A mini 'beast' of the leaf litter the pseudoscorpion Chthonius ischnocheles. This tiny arachnid is just a few millimetres long. It uses its venomous 'pincer palps' to immobilise prey such as mites then covers them with digestive fluid and injests the liquefied remains. They are harmless to humans!

Today we’re making a dead hedge using wood from pruned fruit trees and a downed elder.

Dead wood habitats are extremely important for a whole host of species. We never burn wood or brash or take it off site; it gets turned into dead hedges or log piles.

An excellent morning with the Devon Fly Group at their indoor meeting. Topics ranging from potential flies of Atlantic Rain Forest in UK to key entomologists in the history of Dolichopodidae. Great group who get so much done! #localgroups @guyshrubsole.bsky.social @teamdiptera.bsky.social

Limnellia surturi...a rather smart, rather little shore fly (Ephydridae) on sand outside a rabbit burrow at Cali Heath @yorkswildlife.bsky.social reserve yesterday. Looks to be a new VC record. #Ephydridae #shoreflies @dipteristsforum.bsky.social @ynuorg.bsky.social

I’ve been a supporter of @wwf.org.uk for over 40 years & I think it’s the first time I’ve seen flies in their magazine!

Hoverflies (& 100000s more spp) are not just excellent pollinators as adults, as the larvae are either recyclers of organic waste or predators of your garden pests 🤓🪰

Two men standing behind a desk in a marquee. On the desk is a range of skulls, including some with large deer antlers. The banner behind the desk shows the NNNS logo.

Roger Morris and I are picking out Muscidae from the British collection ahead of the upcoming @dipteristsforum.bsky.social field course for a photo shoot!

Trying to get those awkward features imaged to aid the keys and (hopefully) identifications

So far, we found 16 insects with #Laboulbeniales ectoparasitic microfungi, out of 361 screened ones — marking a prevalence of 4.4%. Not bad at all! Go #TeamLaboul! @taxonexpeditions.bsky.social

Definitely scammy, just instant blocking, a pain though. Hopefully, they've stopped now.

Is anyone else getting hammered by friend requests from America, all pushing UK Driving licences and some sort of card? I've had to block around 20 in the past hour.

I am working with #citizenscientists this weekend in the @taxonexpeditions.bsky.social entomological collection, to screen insects for the presence of ectoparasitic microfungi. This project is supported by @msafungi.bsky.social. #TeamLaboul #Laboulbeniales
