Description
Cocoons of Cotesia species with the remains of a dead parasitized caterpillar
Larvae of Cotesia glomerata emerging from a caterpillar of a Pieris brassicae butterfly

The adults of Cotesia glomerata can reach a length of 3–7 millimetres (0.12–0.28 in). This small braconid wasp is black, with two pairs of wings. It can parasitize a wide range of Pieris butterfly species as host, but Pieris brassicae and Pieris rapae are the main hosts. The adults feed on nectar.[2]

Life cycle

After hatching from the pupae, females mate almost immediately and begin laying eggs.[3] The eggs are laid in the larvae of butterflies known as caterpillars, where the C. glomerata larvae develop; multiple eggs numbering between 16-52 are deposited in each caterpillar.[4] After 15 to 20 days the larvae emerge, killing the parasitised caterpillar. These newly emerged larvae spin cocoons in a cluster on or nearby the host caterpillar; after 7 to 10 days the imago adult wasps hatch from these cocoons. Overall it takes between 22 and 30 days for an egg to develop to full adulthood.[3]

C. glomerata is in turn parasitized by the hyperparasite wasp Lysibia nana.

Distribution

This species is present in most of Europe, in the Afrotropical realm, the Australasian realm, the Nearctic realm, and the Neotropical realm.[5]
