Porrittia galactodactyla (Denis & Schiffermüller, 1775) Species

Last modified: April 16, 2021, 11:46 a.m.

Recorded in Belgium only in 2017 when some unidentified specimens were discovered in an old collection. These specimens were bred from Arctium lappa in 1907, found in HA. In 1941, another specimen was bred from the same foodplant collected in the same area.
Since then, no other specimens have become known in Belgium. Nowadays possibly extinct in our country.
