I'm heading to #PAG33! Come see me at poster P027 - Jan 12th, 3-4:30pm to learn about a field-tested new methodology for creating low-cost and lighting fast species identification PCR assays! github.com/RDRidenbaugh...

Despite working on pine sawflies for over 20 yrs, I just recently learned (thanks to work by @rdridenbaugh.bsky.social) that the tip of the ovipositor lance (the part that cuts into pine needles) is consistently asymmetric, with a thickened cutting edge. So cool!
