Probably at the end of the season, only one male and no females in sight. Dark form as in other populations found further north (the photo is misleading and the specimen already appears discolored).
By the dozen on the main host plants.
I had already known the adult since 2005 in another nearby location. At the time I noticed it was slightly larger and more dotted than the locally abundant Lenisa geminipuncta (whose larva is not green and feeds on Phragmites).
Female. Probably one of the first in the season (but it was 10ºC ambient temperature when and where I found it).
It's a new species for the knowledge of Portuguese fauna.

Green caterpillars found wrapped in nettle leaves.
