Viper's Bugloss Hadena irregularis

(Hufnagel, 1766)

Wingspan 32-36 mm.

Widespread in East Anglia and the London area until the 1960's when it became extinct, the last record being in 1969.

The flight period was June and July, and the habitat preference that of the Breckland district.

Despite the English name, the only foodplant in Britain is the rare and localised Spanish catch-fly (Silene otites), the scarcity of which has undoubtedly contributed to the moth's demise.
