Scoloderus

Scoloderus is a genus of orb-weaver spiders first described by Eugène Simon in 1887.^[2] They primarily feed on nocturnal moths using a ladder-type nest, featuring vertical extensions of sticky orbs above and below the circumference of the primary orb. When a moth strikes the web, it slides down the ladder, leaving behind scales on the sticky silk until it is completely ensnared.^[3]
