Day 9 of my 2025 Favorites: Habronattus alachua (again)

I think this species has featured in every one of my favorites run-downs, and I can't help it. They're perfect: the floof and crimson red face of the boys, and the stripy eye makeup on the lasses ❤️

New paper on bark spiders, who build the largest webs made out of the toughest silk. We show that their extremely tough silk, which is potentially metabolically costly, is limited to large females. Juveniles and males use inferior silk.
New publication!

Orb weavers evolved some of the toughest silk, reaching extremes in bark spiders, genus Caerostris. We investigate sex and stage specific patterns in silk properties and find that extremely tough silk is limited to adult females.

90% of the time when Rashford barks at "something" through the floor level window...it's nothing.

Now and then he gets it right (deer were utterly unbothered by his barking).

Bebe Black-tailed (Odocoileus hemionus columbianus) demonstrates the origin of the moniker!
