Like many apoid wasps, C. fumipennis females mass provision for their cells before laying an egg in them. Adult females provision their cells with beetles of the family Buprestidae. When hunting for buprestid prey, the maximum foraging range of the wasp is estimated at 2 km with an estimated average flight distance of 750 meters from the nest.
In Polistes exclamans, equal sex ratio is obtained when only 46.3% of investment is devoted to females as female wasps are 1.16 times larger than male wasps. [16] In a study done by Strassmann, it was found that sexual investment is female biased, especially during years of high predation and when nests are generally less successful. [16]
Wasps have been modelled in jewellery since at least the nineteenth century, when diamond and emerald wasp brooches were made in gold and silver settings. [80] A fashion for wasp waisted female silhouettes with sharply cinched waistlines emphasizing the wearer's hips and bust arose repeatedly in the nineteenth and twentieth centuries. [81] [82]
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]
The body of a female is c. 2 inches (50 mm) long, with an ovipositor c. 4 inches (100 mm) long. Females of the parasitoid wasp Neoneurus vesculus ovipositing in workers of the ant Formica cunicularia. Parasitized white cabbage larvae showing wasp larvae exiting its body, spinning cocoons. Playback at double speed.
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 ...
