Did you know that in harvesters (Opiliones) either males or females may take care of the eggs? Machado et al. gathered data from the field and literature on parental care in these arachnids, but half their data comes from community science @inaturalist records doi.org/10.1093/zool...

Take a close look at this picture. What an interesting coin or artifact, you probably think 🤔. Such interesting detail, intricately carved or molded 🧐 ... HAHA sucker, you're looking at a SPIDER'S BUTT. Let's meet Cyclocosmia ricketti, the Chinese hourglass spider. CW: spiders & their butts

Anotem essa informação pq raramente ela é repercutida na imprensa quando falam de anistias e dosimetrias: 3 anos após o ocorrido, só restam 179 presos do 8/1.

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).

14 panels showing the process of a drawing from start to end; the first show only the empty lines, and the drawing becomes progressively filled and more detailed. the last panel shows the genitalia with all its features, including pointed ends, a laminate conductor and a coiled embolus.

this was one of my favorite finds in Costa Rica: a mysterious glassy spider with a strange, delicate web. seems to be genus Synotaxus, but I can’t find much else about these little jewels or how they live

under a fluffy white cloud of silk hiding a few white eggs, there’s a translucent pale green spider with a cone-shaped body, the pointy top of which is light yellow instead. the legs of the spider are very slender and long

another such spider sits under a leaf, with its web hanging below; it’s hard to see the strands

closer up, the web is easier to see: many horizontal parallel lines, connected by vertical strands beaded with several droplets(?), making a very orderly but delicate net-like web.

Whether “science is political” depends on how you define “science” & “political” but elections absolutely affect prospects for the progress of scientific research/applications as well as the ability of scientists to work so even in the *narrowest* possible view, institutions of science have a stake

This cool spider is Galianoella leucostigma, the only member of Gallieniellidae in America—all other spiders in the family live in southern Africa and Madagascar. This species only eats ants, and its name honors María Elena Galiano, one of the first and most important arachnologists in Argentina.
