Adaptations These wasps require a tarantula to serve as a host or 'meal" for their larvae. The female wasp will look for a burrow that contains a tarantula and then disturb the webbing around the burrow to coax the tarantula to come out. She stings the tarantula on its underside paralyzing it and drags it down into a burrow. She lays one egg on the paralyzed spider and seals the opening to the burrow. When the egg hatches it eats the still living spider. |
