About Plutella porrectella Linnaeus, 1758
Plutella porrectella is a species of moth in the family Plutellidae. It is found in Europe, the Caucasus, southern Siberia, and Asia Minor. This moth has a wingspan of 14 to 17 millimeters. Its head is ochreous-whitish, marked with a central fuscous line, and the tuft of its palpi is long. The forewings are pale ochreous, with suffused whitish streaks. The costa and dorsum are dotted with blackish coloration. There is a whitish subdorsal longitudinal line that curves sinuate upwards three times; this line is margined above with ochreous-brownish suffusion and scattered blackish scales, which are darkest in the curved depressions. Discal stigmata are usually marked by dark fuscous dashes. The termen is ochreous-brown, and spotted with black. The hindwings are light grey. Full-grown larvae are light green, with a darker dorsal line, black dots, and a head marked with brownish color. Adult moths are active on the wing in May, and have a second active flight period from July to August. The larvae feed on species in the Brassicaceae family, including Hesperis matronalis. They distort or connect the leaves of their host plants using small amounts of silk.
