Bees, Wasps, Ants

Bees, wasps and ants (plus sawflies) are all part of the insect order - Hymenoptera (means 'membrane wings'). A typical hymenopteran has 2 pairs of wings though they are coupled together with tiny hooks so appear as 1 pair. This is a very diverse group with many species which represents a major challenge to those wanting to identify them. We have produced separate resource pages for ants and sawflies, but this still leaves a huge range of species!

Whilst everyone is familiar with bumblebees, the 25 UK species represent just 10% of all the bee species. The remainder are 'solitary' bees that don't work together as a single colony to rear their young. There are some very good resources to bees and the 2015 Field Guide to Bees of Great Britain and Ireland is very helpful.

There is even greater diversity of wasps. As with the bees there are a few social wasps that everyone is familiar with, but these represent just a small fraction of all UK wasps. Solitary wasps such as ichneumons are not at present covered by a popular field guide but there are a number of useful resources to help with identification.

Many members of this group are difficult or impossible to identify from field images. Make sure that your images include the diagnostic features needed to make a definitive identification.
