Chlamydatus evanescens
Family: Miridae

This genus comprises five very small and almost entirely black bugs with rather broad hind femora. Halticus species are similar, but have longer antennae (> body length). The 2nd antennal segment in Chlamydatus is < head width.

In C. evanescens
the forewings are entirely black and the hairs on the hind tibia do not arise from large black spots. The hind femora are dark with a pale apex and the dull forewings are covered with dense yellowish pubescence. The forewings reach at least three quarters the length of the abdomen. Adults and nymphs feed on stonecrops Sedum species in warm, open, sparsely-vegetated habitats. There are several generations a year.

Formerly a great rarity confined to a few sand dune sites in north Wales, it is now found widely throughout much of England as far north as Yorkshire, as well as other parts of Wales. This rapid spread has probably been aided by horticultural introduction on imported Sedum.
