Venturia (wasp) explained

Venturia is a genus of parasitoid wasps belonging to the family Ichneumonidae.^[1]

The genus has cosmopolitan distribution.

Among the species in the genus are:

• Venturia ahlensis Maheshwary, 1977
• Venturia altia (Morley, 1913)
• Venturia canescens (Gravenhorst, 1829)

Parthenogenetic reproduction

Venturia canescens can produce haploid males from unfertilized eggs (arrhenotoky), a form of parthenogenesis.^[2] Females may also produce diploid female offspring by thelytoky, a type of parthenogenesis that involves the production of female progeny in the absence of mating.^[2]
