I'm very excited to announce that I'll be joining the Entomology Department at Penn State University and starting a lab in the summer of 2027!!! The lab will focus on mosquito biology/physiology and mosquito-host interactions and how these impact viral transmission dynamics. More to come soon! 🎉🦟🔬

Implications of successive blood feeding on #dengue virus inhibition by Wolbachia in Aedes aegypti mosquitoes @entomososwin.bsky.social @mallerybreban.bsky.social @brackneylab.bsky.social @chantalvogels.bsky.social @yaleemd.bsky.social

Implications of successive blood feeding on Wolbachia-mediated dengue virus inhibition in Aedes aegypti mosquitoes - Nature Communications
Dengue virus transmission by Ae. aegypti mosquitoes poses a significant public health threat, necessitating innovative control strategies. Here, the authors demonstrate that, while successive blood feeding increases earlier dengue virus dissemination, the inhibitory effects of Wolbachia remain strong, highlighting Wolbachia’s potential to disrupt dengue transmission under natural feeding conditions.

This mosquito is Uranotaenia sapphirina. Most of the time it looks pretty ordinary (right). But get the light just so (left) and it has a little surprise. (The other surprise is that it feeds on leeches and earthworms. No, really!)
Two photographs under a microscope of a mosquito. On the right, a specimen on a paper point; it looks like a pretty ordinary mosquito. On the left, one before mounting shows bright blue reflecting scales in a line down the middle of its thorax and in patches on both sides.

Can any birders help me with an ID? I saw this murre at Crescent Beach SP in Maine on Dec. 28th. I'm btwn a thick-billed murre and a common murre (Merlin thinks thick-billed is more likely and the wing seems to match that better but there's white on the head that looks more like a common murre?
