Tatianaerhynchites aequatus (Linnaeus, 1767)

Male
Widely distributed and common throughout England to mid Yorkshire and Durham, only a few records from Wales. Adults on Rosaceous trees and shrubs, mostly Hawthorn (Crataegus monogyria), Blackthorn (Prunus spinosa) and Crab Apple (Malus sylvestris). but also recorded from Rowan (Sorbus aucuparia) and Medlar (Mespilus germanica). Common around Watford, even in the town centre, on Crataegus. Adults appear shortly after flowering and are present for a few weeks only, they are readily found with the sweep net or beating tray. Seemingly absent from the earlier flowering Prunus spinosa which is abundant in our area and absent from Sorbus aucuparia which is common as a utility species around Watford.

2.6-4.5mm. Head and thorax black with purple/bronze lustre although rostrum in front of antennal insertion without lustre, coarsely punctate with sparse pubescence. Elytra clothed with sparse erect pubescence, red with basal half of interstice 1 black. All striae strongly punctured, punctures at least half the width of interstices, with much finer punctation throughout. Scutellar stria present, scutellum black, as pronotum. Antennae black with segments 4 or 5 to 8 pitchy red, inserted at middle of rostrum. Femora pitchy red, tibiae lighter, tarsi black with all claws appendiculate.
Female rostrum broadened at apex and longer than thorax and head to front of eyes. Male rostrum only slightly broadened, as long as head and thorax.
