I can't remember if I've posted this before, but to bring a bit of holiday cheer, attached is a photo I took of a female Haplalochlaena lunulata threatening at another female that is behind her. The aggressive female is using what I've been calling the "umbrellla" display. You are looking at her ventral surface (mouth visible). This is not the surface that is displayed to the opponent. Still, the blue-rings showing through the web are interesting, so I thought I would share it.
