SPIDER–ANT SYMBIOSIS: COTINUSA SPP. (ARANEIDA: SALTICIDAE) AND TAPINOMA MELANOCEPHALUM (HYMENOPTERA: FORMICIDAE)1

  • Merle Shepard (a1) and Flash Gibson (a2)
Abstract

Salticid spiders of the genus Continusa were present in 61% of the nests of dolichoderine ants (Tapinoma melanocephalum (Fabricius)) which build their nests on the undersides of leaves in the lower forest canopy on the Osa peninsula of Costa Rica. Cutting and displacement of the supporting leaves caused abandonment of 80% of the nests within 4 days and experiments carried out by marking and displacing the spider indicated their tenacity to the ant nest. T. melanocephalum nests which contained spiders were more successful in terms of the brood to adult ratio.
