Female C. fumipennis Male C. Fumipennis. Cerceris fumipennis is distinguished by five conspicuous characteristics: It is large, about the size of common yellow jacket wasps. It has dark smoky, blue/black wings. The wasp's body is predominantly black except for a few yellow markings. It has a conspicuous, single broad creamy yellow abdominal band.
Winged female and wingless male. Blastophaga psenes is a wasp species in the genus Blastophaga. It pollinates the common fig Ficus carica and the closely related Ficus palmata. [3] These wasps breed in figs without the need for a colony or nest, and the adults live for only a few days or weeks. [4]
However, the majority of wasp species are solitary, with each adult female living and breeding independently. Females typically have an ovipositor for laying eggs in or near a food source for the larvae, though in the Aculeata the ovipositor is often modified instead into a sting used for defense or prey capture. Wasps play many ecological roles.
On average, female forewing length lies between 2.5 and 3 cm (0.98 and 1.18 in). [7] Females are larger than males and live for a year, a time just long enough to produce a brood, whereas the males die in only a few days, just enough time to impregnate a female. [ 6 ]
The female is about 22 mm long; the male is smaller and lacks a stinger. [2] Males can be less than half of a female in size if emerging from a smaller or a superparasitized host. [ 3 ] The species undergoes four larval stages, where the initial younger larvae can be seen as external hemolymph-feeders on the paralysed roach's leg, and the last ...

In all, perhaps 700,000 or so parasitoid wasp species are estimated to exist, but it’s probable that the number is far higher. Even the parasitoids are not immune to victimization.
