A nice range of species seen in the western Mourne Mountains in Co. Down recently, including Andrena tarsata, Lasioglossum rufitarse and Dasysyrphus pinastri, which was a new one for me.

Hoverfly Epistrophe nitidicollis, a female egg laying around Aphis sambuci colony on Elder in Kildavin, Co. Carlow over the weekend. Only the 12th Irish record and first for Carlow.

That looks like a Pemphredon wasp, but it's hard to tell.

Ancistrocerus gazella is likely, but it's too difficult to say for certain as there are other possibilities.

Yes, good find! Please record 😁

Always interrupt a phone call with your mother to investigate a black dot gliding down a downpipe. One day, it'll be something worth getting excited about that has you running for the camera. Saw my first ever Kidney-spot Ladybird tonight. It's just the second record of one for Limerick.

Yes, once they find some mud with the correct moisture content they'll keep coming back.

Couple of beetles from the dunes at The Raven, Co. Wexford today. Phylan gibbus (Tenebrionidae), Melanimon tibialis (Tenebrionidae) & Charagmus griseus (Curculionidae).

I'd agree John. The foodplant can also provide a clue. Do you know what it was on?

It's the only Priocnemis species that flies in April. The rest generally don't appear until late May. Can you record it with NBDC?

This pic from a Cheilosia hoverfly unknown to me is from 14 May 2019. Sent the specimen to a specialist, who found to be an undescribed species. Ever since then I've named it 'Cheilosia new.sp'. Finally, I'm happy to learn that it has been already named for science (can't reveal the name so far) .

Large Sallow Mining Bee (Andrena apicata) female and male seen along the river Barrow in Carlow recently. An underrecorded species in Ireland, but the populations in this area seem to be quite strong and it was the most abundant mining bee during my visit. It's a willow specialist, peaking in April.

A nice surprise this week was finding Andrena praecox locally in Co. Armagh. This is the second NI record of this early spring species, which is generally very scarce north of Dublin. It's probably underrecorded due to its early flight period and habit of foraging high up in willows.

Owen Beckett @obeckett98.bsky.social · 26/03/2025
Your other bee is likely to be Andrena scotica from what I can, but I can't rule out Andrena trimmerana.

Two female Cheilosia grossa seen in Dublin and Wicklow recently. An attractive yet overlooked hoverfly which flies in March and April. The larvae mine thistles, so it's worth having a look on dandelions or willows growing close to thistle rosettes: species.biodiversityireland.ie/profile.php?...

Owen Beckett @obeckett98.bsky.social · 20/03/2025
Andrena apicata, Andrena praecox and Andrena clarkella males observed in Cos. Armagh, Dublin and Wicklow over the past week. The females shouldn't be too far behind, especially now that the pollen source of these three species, willow catkins, are starting to appear en masse.

If they're in a sunny spot, root plates can offer great nesting sites for solitary bees (and wasps later in the season) because they're equivalent to the bare ground of a vertical bank.

Three bumblebee species, Bombus lucorum, Bombus terrestris and the most notable one, Bombus hypnorum, enjoying the winter heather in Armagh today. This species only arrived in Ireland around 10 years ago, but is now quite common in the northeast in particular.

Anthophora hispanica es mi especie favorita de ese género. Tamaño de abejorro y velocidad de avión. Con suerte la podréis ver por estas fechas alredededor de plantas de Erophaca baetica. Aquí un macho repostando un instante, sin parar el motor. Lo mejor de mi día de abejeo.

Velvet ants (Mutillidae and Myrmosidae) are pretty cool creatures! Despite their name, they are actually wasps, and not ants. (Most) males are winged, and females do not have wings.

Are you in North America Matt? It looks a bit like Andrena nigerrima. Andrena nigra and Andrena nigricula may also be possible. I'm not too familiar with Nearctic Andrena, but it might be a useful starting point 🙂

2024 Highlights #5. One of the best wasp-mimics I've ever seen: Temnostoma vespiforme, a spectacular hoverfly I found in Brittany, France while cycling along the Nantes-Brest canal. It's got all the right markings and even waves its front legs to look like long wasp antennae. #Diptera #Hoverfly

It is an irrefutable fact that some endangered insects can't be identified without checking them under a microscope. How can we ever hope to understand their ecological requirements if you can't identify them? To illustrate this, these three bees are different species. One rare, two common.

Spruce Cone Bug (Gastrodes abietum) seen in Loughgall, Co Armagh. This species was first found in Ireland by @joshecology.bsky.social earlier this year and has since been found at three sites. It lives on the cones of Norway Spruce, so it's probably more widespread than current records suggest.

It's hard not to get dragged down by the negativity on Twitter, so thought I'd give this a go. Here's a lovely Heather Mining Bee (Andrena fuscipes) from the Mourne Mountains, Co. Down last year.
