  • J. O. Howell
  • R. L. Pienkowski


C. kincaidii, an ectoparasite ofTetragnatha laboriosaHentz, was found most commonly in spring and fall. Peak parasitism was 18%. They appeared to oviposit only on middle instar spiderlings, and winter as larvae attached to spiders.

C. kincaidii, un ectoparasite deTetragnatha laboriosaHentz, a été trouvé très communément au printemps et en automne avec un taux de parasitisme maximum de 18%. Il semble pondre seulement sur les stades juvéniles moyens de l’araignée et hiverner à l’état de larves fixées aux araignées adultes.
