Hymenoptera - The Sawflies, Bees, Ants and Wasps (cont.)

The form of the eyes may differ, in some families the inner margins may be strongly emarginate (notched or indented).
In review, when submitting a member of the Hymenoptera for further identification, include digital images of the front wings paying particular attention to venation. Images of the antennae, shape of the pronotum in profile, tibial spurs and number of trochanter segments are also useful. Form of the tarsi may be difficult to include initially but may be needed if additional images are required. One image may be able to convey more than one characteristic.
