Mimetidae usually hunt by picking at the strands on their prey's web to simulate the movements of either a trapped insect or a potential mate. When their prey comes to investigate, they are instead captured and eaten. Some mimetids have been observed to feed on insects as well. The spider-feeding habit presents problems in mating, and little is known about how the males court females to avoid being eaten. However, some male mimetids in the genus ''Gelanor'', found in South America, have enormously long appendages which they use to inseminate females.

Distribution

Pirate spiders are found in forests all around the globe, wherein the highest diversity is found in Central and Tropical South America.

Taxonomy

The Mimetidae are sometimes taxonomically grouped in the superfamilies
