  1. 💁🏻‍♀️ 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.

    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

  4. 🔎 MYSTERY EGGS 🕷️
    ¿Who’s inside this webbed capsule?

    I found this abandoned egg sac, and I’m almost certain it belongs to a Salticid.

    But Salticidae is a huge family... so WHO exactly is inside?

    My guess, based on the shape, location, and local species, is Astia maculata.

    But it could just as easily be Servaea, Clynotis, Apricia… or someone unexpected...

    I’m really excited to find out 🐣👀
