They are diurnal and lead an exposed and conspicuous lifestyle on herbaceous vegetation, typically in wooded situations with a supply of decaying logs and fallen timber.

Adults are short-lived and have a brief season, usually appearing in April, becoming common through May and early June and only rarely encountered later.

Mating occurs early in the season and females oviposit among or beneath areas of dead bark on a range of broadleaf wood, more especially Oak and Beech, usually on fallen timber.

In the UK it is generally common in southeast England but more local and sporadic further north to the Lake District and is generally absent from the West Country and the west of Wales.

Rarely recorded in Leicestershire and Rutland.
