Typhaeus typhoeus x3 this morning in Bengeo garden. Males are very distinctive with their 3 prongs.

Species is able to exploit winter availability of dung by digging much deeper burrows in sandy soil. These remain warm even in coldest months of January & February. #MinotaurBeetle #attractedtolight

This represents c38% of hoverfly species recorded in UK. It is difficult to predict which species may yet appear here. The only common features of these 4 new species is that I have previously recorded them within 2 miles of here at major wildlife sites. Dogwood & Ivy yet again featured.

Wonderful species, 15 records in garden + 2 further records locally. Always single males. Hertford-Broxbourne area is one of its national strongholds.

Povolnya leucapennella

Povolnya leucapennella last Friday in Bengeo, associated with evergreen oaks such as Holm Oak (Quercus ilex). Very scarce species in Herts. @bc-hertsmiddx.bsky.social #teammoth

Lovely species. Very restricted distribution in Herts associated with gravel or sometimes on chalk. Have recorded it once at Kings Meads & often at Waterford Heath, former gravel pit where it is surprisingly common.

Good record. Nocturnal species that seems to be recorded mostly from light traps. Distribution appears to be very patchy with few hotspots.

Super shot of Goldcrest. Possibly braconid wasp but not really able to make out enough detail of prey item.

Soldierflies are much less well known than hoverflies but some species are highly colourful.

Kings Meads, local wetland to Hertford, is county stronghold for species where it is abundant. Elsewhere in Herts, it is rare.

Myathropa florea male

Every October without fail, hoverfly Myathropa florea ♂ start landing on my head on sunny days. Their buzz is very distinctive & with little coaxing they can be persuaded to stay long enough on my hat to be photographed. Today in Bengeo garden.

One of the most incredible WTF!! moments I have witnessed in 41 years birding Belvide. 8 White-rumped Sandpiper on the north shore between 4pm-5.30pm. Just short of a British Record of 11 on the outer Hebrides. Thought I'd lost the plot when I saw them. Still pinching myself. #UKbirding

Three records of Phaeostigma notata in garden including two this year. Xanthostigma xanthostigma is much commoner here & is recorded annually. Also single record of Atlantoraphidia maculicollis below Scots Pine. Nearly all records follow windy weather when snakeflies are displaced from canopy.
