- Abstract
A trap-nesting study provided the first documentation of brood parasitism in Dipogon nagasei and in D. iwatai. Dipogon nagasei was found to brood parasitize D. sperconsus, D. conspersus, D. inconspersus, and D. bifasciatus. Dipogon iwatai brood parasitized D. sperconsus, D. conspersus, D. romankovae, and Auplopus carbonarius. Both brood parasitic species are with the subgenus Nipponodipogon, whereas all five Dipogon hosts are in the subgenus Deuteragenia. Comparison of their ecological features revealed that brood parasitism in D. nagasei is considerably more derived than in D. iwatai. Of particular note is the fact that in D. nagasei the female routinely lays up to five eggs on a single host spider, all of which develop into adult wasps without larval cannibalism; almost all Pompilidae previously studied lay only one egg on a host spider.
