We re-analyzed the sex pheromone of a black widow using multidimensional chromatographic mass spectrometry, then measured the newly identified sexual signals in the field for a year. Open Access @ Journal of Chemical Ecology.

Whip spider (Paraphrynus laevifrons) covered with chloropid fly puparia. The parasitoid fly attacks the eggs carried by the female. When done, the maggots climb on the "childless" mom's back and pupate. She protects them during this period thanks to her motherly instincts.

The process of drawing a spider male genitalia for taxonomic description. ~2:30 hours in total (only the filling; the lines in the camera lucida might have taken an additional hour or so).

Titiotus heberti from the mountains of Kern County CA. the large hook-like structure on the pedipalps (in the front) is called the "retrolateral tibial apophysis" (=RTA). turns out that this feature defines a large natural group of spiders

Here are your Friday Scorpion Fingers. This scorp is in the genus Serradigitus, or sawfinger scorpions. They are called this not because they will saw off your finger, but for the uniform, saw-like teeth on their chelae (singular chela), which is the science-y word for their pincers. 🐙 #invertebrate
