2010-08-25 Vienna XXII. district (Lobau brownlands, 155 m AMSL).Flower and fruit; here on Solidago gigantea (subsp. serotina): an untypical host.I've found some who died on Solidago before they could flower and fruit: so obviously it isn't too vital on Solidago, but it can survive there.German name: Nessel-Teufelszwirn (-Seide)For more photos from the same habitat click here!
