Metallic green Jumping spider

Siler semiglaucus


Saying hello to everyone!!! Brilliantly colored jumping spider. About 5mm size. They are almost always found near small black ant colonies. These ants do not seem to attack them. These spiders also prey on the ants, their larvae and their eggs. Here one female specimen is seen stealing an ant larva.


Spotted on a banana plant near an ant colony.

As sunnyjosef mentioned, I also thought it looks like the spider is trying to mimic antennae by using its front legs. Jumping spiders are truly amazing.

Thank you Leuba for your comments. I have read somewhere that there are several kind of mimicry among these critters.... Some visually mimic others while some others are chemically masking their identity. Mysterious and wonderful world indeed...!
