This species is very similar in appearance, size (4-7 mm) and nesting habits to Formica fusca, but was firmly described and keyed by Yarrow in I954. Workers differ from those of F. fusca by the presence of short stubby hairs on the promesonotal dorsum which is usually bare in F. fusca, and there are good diagnostic differences in males and queens (Skinner & A llen 1990).
Editor's note. The original profile combined the two species F. fusca and F. lemani but this… Read more

If you are a member of the advanced site editor role, then you can access the species account importer. Before doing this you need to prepare the atlas texts ready to copy in for the species you want to import. Adhere to the following rules:
A large, attractive mining bee which occurs in two colour forms, more noticeably in females than in males. In females the most frequent form has a largely black gaster, whereas in the other form, tergites 1-2 (occasionally 3) and sternite 2 are conspicuously marked with red (figured by Westrich (1989)). Males usually have black gasters, though in some, tergites 1-3 are posteriorly marked with red. Andrena hattorfiana, in common with A. marginata Fabricius, is strongly associated with scabious… Read more
A scarce southern species that resembles a red and black ichneumon wasp. Packer (1987) lists records and observations to the early 1980s (as Alysson lunicornis).
A distinctive wasp with its yellow-banded, waisted abdomen combined with distinctive dark smudges on the forewing. Previously known as Gorytes bicinctus.
Previously classified in the genera Alysson and Dienoplus. A small red and black wasp, typically with a white scutellum and three white spots on the abdomen rendering it distinctive. Usually encountered in dry sandy locations where it is a frog-hopper predator.
The scarcer and smaller of our two Argogorytes wasps, but seemingly with a similar biology to A. mystaceus. Often cited as Gorytes campestris (Linnaeus, 1761) in older literature.
Much information on the behaviour of Nysson and related genera is given by Evans (1966), although the nomenclature is now out of date.
