Ah glorious summer is here, a time for reflection and relaxation when a person can kick back and…think about really beautifully colored parasitoid wasps. This is the ruby-tailed Wasp (Chrysis ignita) which lives in Western Europe and Great Britain. Although the wasp has a long stinger, it has no sting, so people who are afraid of bees and hornets can stop shuddering and enjoy the lovely iridescent blue-greens and purples of this jaunty little wasp. When the ruby-tailed Wasp is feeling alarmed, frightened, or just plain overwhelmed by modern life, it can curl into a protective ball. Although these wasps are very pretty, their behavior is less than beautiful–for they are a sort of cuckoo wasp. They find the nest of their hosts (ruby tailed wasps parasitize masonry bees) and lay their own eggs among the eggs of their victims. The different clutches of eggs hatch at the same time and the wasp larvae devour the bee larvae before morphing into adult insects. So, like nature itself, the ruby-tailed wasp is simultaneously beautiful and horrifying.
