🕷️ A jumping spider that nurses its young with milk — 4x the protein of cow's milk

Female Toxeus magnus spiders secrete a milk-like fluid from their egg-laying opening for nearly 40 days after hatching. Newborns drink nothing else for the first 20 days and die within 11 days if the mother's milk supply is blocked.

Even after spiderlings learn to hunt at day 20, they keep nursing alongside their own kills for another three weeks. Daughters are allowed to return to the nest after reaching adulthood, but adult sons are attacked if they try.

This subverts the long-held assumption that lactation and extended milk-provisioning are exclusive to mammals.

Our Summer rains in Tucson bring out awesome arthropods; here are 2 of my favorites I drew in my Perpetual Journal: Red Velvet Mite & Ironclad Beetle. See more on my latest blog post https://paulaborchardt.substack.com/p/while-april-showers-bring-may-flowers

💁🏻‍♀️ TIL: 🕷️🕸️ Researchers from #Macquarie University discovered a new ballista #spider species in #Queensland’s #CapeYork #rainforest that builds a spring-loaded web snare targeting green tree #ants.

When an ant bites the cone, tension lines fire it into the web at 1,367 m/s² – roughly 140 G – making this the most power-dense biological catapult known. The spider’s use of pheromone-mimicking silk represents a #hunting strategy not seen before in any #arachnid.

Black Windows Freak Me Out, Still

Growing up in Washington, black widow spiders were something exotic from far away lands. Then I moved to California and started finding them in place I did not want.

I can still remember seeing my first one when we lived in Orange. It

More observations from May:
An Opisthoncus, a Proszynellus, an Arasia mollicoma, and a Plautia.
