I have found only one previous record of adult Anisoptera feeding on spiders: A. WARREN (1915, Coll. Hawaii Publ. Bull. 3; 33-34) cites two observations for Pantala flavescens (Fabr.). During august, 1978, I observed a halfgrown specimen of the jumping spider Phidippus pulcherrimus Keyserling on a fence post along the edge of a pasture in southeast Gainesville, Florida, USA. I captured the spider and was observing it when it jumped from my hand, trailing a dragline behind it. Before it reached the ground, it was caught in midair by E. simplicicollis. Apparently E. simplicicollis may associate with large animals and feed on insects disturbed by these animals (S.W. Dunkle, personal communication). In this case, I was the large animal and inadvertently I provided the prey.
