This spider had a giant web that was catching mostly monarch butterflies in Central Texas. It appears to be some sort of a crab-like creature with 6 spikes around the top portion. The markings on the top are off-white with black, and on the bottom… look strangely reminiscent of the side of a monarch, with little dots. When it’s threatened, it hunches down and folds up into a nondescript little ball. What on earth??
