Cool work by the lab of @waspvenom.bsky.social on host-associated #speciation!
New paper from the Martinson Lab! A fun study where we find a nice example of cascading speciation and describe three new species. Plus some exciting data to suggest that ecological guild may influence the impacts of host-associated differentiation. A 🧵. #galls #insects 🧪 doi.org/10.1111/mec....

The geometrid moth Drepanogynis insciata was only known from two historical specimens collected before 1879. Now, it has been rediscovered in South Africa's Western Cape.
