Life Cycle

to development occurs within or on the ; laboratory studies indicate development from egg to adult takes approximately 15.5 days when reared on at optimal temperatures. Sex ratio is approximately 45:55 (male:female). stages exhibit temperature-dependent developmental rates compatible with thermal response theory for .

Behavior

Females structures with their when searching for . Exhibits : females can learn to respond to chemical cues (such as methyl parahydroxybenzoate) associated with hosts after exposure, though naive females reared from uncontaminated hosts do not respond to these cues initially.
