A medium-sized (4.5 to 5.5 mm) black mirid bug covered in flattened scale-like pale hairs which may appear golden.  There are two very similar species but they use different host plants, and for that reason it is very important to state the host plant on any record for this species.   Heterocordylus tibialis is associated with Broom. It can be distinguished by the brownish tibiae and by the width of the 2nd antennal segment, which is only slightly thickened towards the apex.

Heterocordylus genistae is similar but uses Dyer's Greenweed, not Broom.

Unless identified by a recognised expert, a photo is required. If the photo doesn't show the key ID features then in the comments box describe the size and identifying characters you have observed. For this species the host plant must be stated as part of the record.

Usually found on Broom.

Adult: May to July

Nymphs become adult early in the season, although rarely survive beyond mid-summer.

A common bug throughout Britain on Broom, the only host plant.

Status in Leicestershire and Rutland not known but certainly seems to be common on Broom at Fosse Meadows.
