Wasps & Sawflies (Hymenoptera) @ Peartree

Hymenoptera is diverse group of insects that includes bees, wasps, sawflies and ants, with around 7000 British species, of which the majority are wasps. Many of these, including Braconid, Chalcid and Ichneumonid wasps, are parasitic on other insects, although some, including Sawflies and some Chalcid Wasps, are plant feeders. The very familiar Common Wasp and Hornet are predatory species, but we don't have any photos of these at Peartree Green yet (so if you spot any do send us your photos!). Here are some of the wasps and sawflies that we do have photos of...

Their larvae are parasitoids of solitary bees. The adult female's long ovipositor enables her to inject eggs into the brood cells deep in a bee nest
