End of July I still found caterpillars in the dried up garden, among others this Small white (Pieris rapae) ^[1] on the last remaining somewhat green leaves of the Garlic mustard (Alliara petiolata).

The caterpillars of the small white can be identified based on ^[2]:

• a green body with small black specks
• rather dense short hairs covering the body
• a yellow back stripe over the length of the body
• black lined spiracles on the sides

In 2020 the species is present on the the plant as well.
