Orb Weaver Spider (Argiope savignyi)

Posted on Dec 11, 2014

While walking trails and getting acclimated in Costa Rica today I came across this Orb Weaver spider (Argiope savignyi). It had recently captured some fly species in its web. I instantly recognized this spider because of a documented case of it eating a Proboscis Bat (Rhynchonycteris naso). It managed to encase the bat with its silk over the course of the day. The bat became tired and was able to be consumed eventually.
