Chapter Summary

Eumerus are small to medium-sized hoverflies. Most are thermophilous and can be found in grasslands and at the borders of woods and bushes, often near the larval food plants. Most species fly quickly near the ground, which makes them difficult to spot. The larvae mine through bulbs (e.g. Allium) and are considered pests in commercial bulb plantations. Eumerus are either blackish flies with silvery spots on the tergites or reddish flies with a blackish thorax. Femur 3 is swollen and without a triangular tooth below the apex. There is no facial knob on the head and the mouth edge only projects slightly. The key is based on Van der Goot, Seguy and study of specimens at the Zoological Museum of Amsterdam (ZMAN). E. elaverensis, E. amoenus and E. pulchellus are provisionally added. The first is added from the description of Seguy, the latter two based on specimens in the ZMAN.
