A very striking insect, particularly females with a red head contrasting with a metallic dark blue body. No records until the 21st century, since when recorded from Cringleford Woods (2006), Cranwich Hall (2009), Weeting Heath (2018) and Saddlers Wood, North Walsham (2019). The three records with full details have all been in April.
