Genus Empria


The Empria are characterised within the Allantinae by the following features. The abdomen is mostly black with a pair of silver/grey flecks on the basal tergites either side of the midline. The malar gap is at least half as long as the width of an antennal socket. The second antennal segment is shorter than the malar gap. The pedicel is as wide as or wider than long. The mesepisternum is smooth and unsculptured on the dorsal half.

There are 56 species of Empria globally with the majority being found in the palaearctic region. Fifteen species occur in Britain of which 10 also occur in Ireland. Most are widely distributed though Empria fletcheri and Empria alpina appear to have a montane, northerly distribution.

The larvae are free feeders on members of the rosaceae family and birch and willows.
