I found a cricket leech after work today! :0 Cricket leeches are the larval form of solitary wasps in the family Rhopalosomatidae, which is the ancestral branch of all paper and potter wasps.
A photo of a dark bean-like entity stuck to the side of a cricket between its body and left hind leg. The cricket's posture looks like if a basketball player was trying to hide the fact that they got bit by a tick the size of a poodle, carrying it casually under one arm. The wasp may not directly kill its host, but the loss of so much hemolymph will likely reduce the cricket's lifespan. A photo of the same unfortunate pair from further away, so you can see the scale of the parasite. The cricket is gravid and will likely lay her eggs soon, parasitic wasp be damned. #girlpower

Humaning.
A four-panel comic. In panel 1, a Northern Cardinal and American Goldfinch perch above a busy crowd in a city, looking down. The cardinal says "It's a nice day to go humaning." The goldfinch says "Just look at them. Majestic." In panel 2, a close-up of the two birds. The cardinal says "Nobody tells you that you'll reach a certain age and suddenly get into humaning. I hit 3 years old, and then bam."The birds are looking out over the crowd scene. In panel 3, the cardinal says "Their calls sound funny to us, but each one has a unique meaning." Below, people are saying various things: "I'm tired." "Where's my phone?" "I'd murder a burrito." In panel 4, the birds look down excitedly at a man walking by. The cardinal says "Wait, is that a guy who got dressed in the dark and put his shirt on inside out and backwards?" And the goldfinch exclaims, "Holy... that's a lifer!"
