A parasitic wasp has injected her eggs into a caterpillar — and now they’re ready to hatch.
Today, warden Erik van der Spek on Texel island in the Netherlands writes that a wasp species has been discovered on Texel which had never been seen in the Netherlands before. It is Neorhacodes enslini.
This small parasitic wasp species of the Ichneumonidae family lays it eggs in the nests of bigger wasp species.
