90% of the time when Rashford barks at "something" through the floor level window...it's nothing.
Now and then he gets it right (deer were utterly unbothered by his barking).
Bebe Black-tailed (Odocoileus hemionus columbianus) demonstrates the origin of the moniker!

#Bugsky 🐙🌿 Earwig Egg Update! Yesterday I took a photo of earwig eggs, and when I lifted the rock today, they were hatching. The new babies are transparent except for their compound eyes and mandibles; those were the orange spots you could see on the eggs yesterday. Check out this cropped photo--

We found oyster spiders today during my oyster lab field trip for my Invertebrate Zoology class! These are marine spiders! They have special setae (hairs) that trap air and let them live underwater. #invertebrates #spider

I'm still on strike as a PT CUPE professor at SMU, and it's a little mind-boggling how much money SMU has made off of my students. We are now up to $24,272 that my students have paid and had no education in return. That's 2 whole domestic students' worth of tuition they just created out of nothing.
