Lepidocyrtus violaceus belongs to the group of Lepidocyrtus with strong blue pigment on the head, thorax, abdomen and legs. The second thoracic segment is not prominent (Fig. 1). There are scales on the legs and on the first (ant1) and second (ant2) segments of the antennae, but NOT on ant3 and ant4 (Fig. 2). Although Steve reported having seen a 2mm specimen from Ireland, English specimens rarely exceed 1.6 mm.
Lepidocyrtus violaceus may be more common than indicated on the map as it has probably been overlooked in the past. Some of the slides in the NHML collection labelled 'Lepidocyrtus cyaneus' have scales on the legs and antennae and are clearly Lepidocyrtus violaceus.
