Hi Bluesky! Apparently there's been a massive migration from the other site, so I want to take a second to reintroduce myself. #HiSciSky
I'm Johanna! I'm an entomology PhD student at the University of Illinois at Urbana-Champaign. Currently, my research is on wing evolution in cockroaches!

Was reminded of this awesome “essay” by T Josek from many moons ago - when us scientists still used the bird website.

T’s use of hashtags here is pretty much perfect. Informative and funny.

Some of the entries are - uhm - timely? (Note: October 1936)

In honour of the excellent Blattodeology episode of @ologies.bsky.social podcast, please enjoy these veeeeerrrry fancy Mardi Gras cockroaches (Polyzosteria mitchelli) from arid WA:

The stripes!
The yellow shorts!
The blue socks!
🌏🪳 #wildOz
(Go listen to the episode www.alieward.com/ologies/blat...)
A large and spectacular Mardi Gras cockroach photographed walking along a small wooden log. The bright colours of the diurnal insect stand out agains the mottled grey background of the log and leaflitter. The mardi gras cockroach is a rich, shiny black brown, each segment carrying a horizontal bold yellow stripe with two more yellow stripes running from top to bottom along the each side of the back. The cockroach has bright blue lower legs with dark stripes. Definitely off to a party!! This Mardi Gras cockroach is off to a sandy bush doof! Captured from a different angle, you can see the full impact of the yellow stripes along the sclerites or plates covering each segment, from thorax to end of abdomen. Also clearer are the fancy yellow shorts and blue knee-high socks that complete the party ensemble.
