Stylopization, or parasitism by species of the insect order Strepsiptera, is documented in two species of the sphecid wasp, Ammophila, including, A. fernaldi (Murray, 1938) and A. pictipennis Walsh, 1869. A case of superparasitism by six strepsipterans in one A. pictipennis wasp and a neotenous strepsipteran are documented.
In a fifteen year period, the observed life span of both male and female Sphex pensylvanicus was documented in an aggregation of these wasps behind a retaining wall on a residential lot in Sioux City, Iowa USA. In addition early season emergence of the males before the females (protandry) and instances of male territorial behavior were also confirmed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
