Each social wasp colony includes a queen and a number of female workers with varying degrees of sterility relative to the queen. In temperate social species, colonies usually last only one year, dying at the onset of winter.
Polistes aurifer, the golden paper wasp, [3] is a species of paper wasp in the genus Polistes of the family Vespidae. [ 1 ] [ 4 ] [ 5 ] It occurs in the western part of North America, from southern Canada through the United States to northern Mexico .

Female X. vesparum are markedly different from their male counterparts. They display a high degree of neoteny, and are permanent endoparasites of their hosts.They reside in the wasp's body cavity and never develop mouthparts, legs, eyes or wings, and their only form of genitalia is the ventral opening where males can inseminate them, as well as being the point of larval escape.

Despite the toxic effects to mammalian cells, mastoparan is also a potential antibiotic template due to its potent antimicrobial activity. In design study performed by Irazazabal and co-workers (2016), [4] it was demonstrated that the inclusion of an isoleucine and an arginine residue at positions 5 and 8 respectively [I5, R8], dramatically reduced the toxicity of mastoparan, turning it into a ...

Adult wasps lay their eggs in tobacco hornworm (Manduca sexta) and tomato hornworm (Manduca quinquemaculata) larvae in their 2nd or 3rd instar (each instar is a stage between moltings, i.e. the second instar is the life stage after the first molt and before the second molting) and at the same time injects symbiotic viruses into the hemocoel of the host along with some venom.
