Fantastic to have another glowing review of the Flyble from such a big name in ecology and conservation. Thank you @markavery.bsky.social ! Yes I wish I'd had our book for my lockdown 'backyard bioblitz' too!

Sunday book review: A Photographic Guide to Flies of Britain and Ireland by Falk, @gailashton.bsky.social @rdimond.bsky.social & Creed Review: markavery.info/2026/07/05/s... Publisher: @naturebureau.bsky.social "1500 pin-sharp images of 1300 UK species" "An amazing celebration of insect diversity"

Struggling to sleep in this heat but I've spotted one of my home's nocturnal residents - a Spitting Spider (Scytodes thoracica). Have seen at least 3 in the house this weekend.

All right cockers? I got home for Cockchafer o'clock tonight! Great to see these big, bumbling beetles around. Likely emerging from the neighbour's lawns. You can see where they've been munching the young ash leaves too.

Rather enamored with the big Banded Damoiselle nymphs that kids caught on our river dips in the Stort today for #HertsRiversWeek Also gratifying to find shedloads of Blue-winged olive mayfly nymphs and several caddis and Bullheads, showing that the water here is still of decent quality.

My sincerest thanks and condolences to all the staff and volunteers who cleared up Britain's greenspaces today after the heatwave bank holiday madness! Fighting the real, physical, shameless blight on the country. This pic was far from the worst - at least the culprits bothered to find a bin.

Messing about by the river today helping to build up a brash berm in the Stort with the Friends of Castle Park. These features create a more dynamic flow, reduce soil erosion, vegetate into bankside habitat and offer refuge for fish and aquatic invertebrates. All with entirely natural materials.

Recently gave a talk to BTO Youth on starting out with identifying insects in Britain and Ireland. Pleased to see how keen young ornithologists are to engage with the world of insects! I'd be happy to give this again if any natural history groups are interested- it was a lot to put together!

Lovely to find my first nest of the shell-nesting Red-tailed Mason Bee (Osmia bicolor) on a Herts Invertebrate Project outing to Sheethanger Common yesterday. One of a few nice finds on this former golf course near Hemel Hempstead, now owned and managed for nature by the Boxmoor Trust.

Decided to take a trip to some North London gardens on my day off. Wasn't expecting many insects in the overcast conditions, so the specialist Large Scissor Bee (Chelostoma florisomne) at Myddelton House and my 1st adult Bronze Shieldbug at Culpeper Community Gardens were nice surprises!

Two males of the scarce Hornet Grabber (Conops vesicularis) in Gamlingay Wood LNR, S. Cambridgeshire this morning. A sexually dimorphic fly, I've included a photo of a female photographed in my garden earlier this month to illustrate the difference. #Diptera #Flies

Is this the world's worst photo of a Wasp-banded Combhorn Cranefly (Ctenophora flaveolata)? Quite possibly. Am I dead chuffed to have spotted it way up in a standing dead oak? Absolutely! My first encounter with this striking, scarce species on our Herts Invertebrate Project outing to Hudnall Park.

Photo of a dead tree trunk largely missing its bark save for a patch on the upper right. A yellow and black cranefly is sat on the trunk just at the bottom left edge of the bark.

I am absolutely made up about this 'Flyble' review in British Wildlife by none other than Brett Westwood! A publication and a naturalist I've had a huge amount of respect for since my uni days. It's really gratifying to see the reception of this book after so much hard work.

Thrilled to find a gathering of these Mammoth Wasps (Megascolia maculata) in Spain, busily nectaring with males pursuing the massive females. Their bold colours, violet wings and jack o'lantern faces look fantastic! They're Europe's largest wasps, with larvae parasitising chafer grubs.

An impressive African Giant Mantis (Sphodromantis viridis) near Almeria, Spain. Identifiable by her whitevwing spots. Non-native to Europe but still exciting to see. She'd found a very productive ambush perch amongst Giant Fennel flowers.

Staying with a good friend in Almeria and of course enjoying the local insect life. Spanish Festoon and the shell-nesting bee Rhodanthidium sticticum have been highlights.
