Euura glutinosae... #yorkshiresawflies which feed on Alder. A common species at Cali Heath Yorkshire Wildlife Trust reserve. YNU

2023 was a good year early on for #Yorkshiresawflies with new county records including...(clockwise from top left) Euura sagmarius, E. krausi, Pristiphora amphibola and P. alpestris. Thanks to all YNU members and others for their records. flickr.com/photos/5216302…

Nematus alniastri on Alder at Cali Heath Yorkshire Wildlife Trust reserve recently. Numbers of larvae of #yorkshiresawflies still low, but have picked up the last few weeks, so maybe delayed emergence following heat of late summer? YNU

Quite a decent variety of #yorkshiresawflies appearing locally now. Clockwise from top left...Euura pavida, Heterarthrus microcephalus, Nematus cf. acuminatus and Tenthredo scrophulariae. All within a few square metres at #AllerthorpeCommon this am. YNU

The early sawfly Dolerus anthracinus has not been recorded for 50+ years in Yorkshire, but is probably here still...please collect any black Dolerus from chalk grassland over next few weeks and send to me. sawflies.org.uk/dolerus-poodol… #YorkshireSawflies Dan Lombard YNU

A female Neodiprion sertifer just emerged from larvae found by Adam Parker 🤟🤖 is in need of biscuits. at a York P&R and collected by me back in May. Also have a couple of males emerged, but too flighty for a photo. #yorkshiresawflies YNU
