There are two picture-winged flies that live exclusively on Burdock, using the plant for their larvae to munch on. The Banded burdock fly (Terellia tussilaginis) is one (see my blog Burdock beasties, August 2020) and today’s featured fly is the other. This is Tephritis bardanae, a tiny fruit fly that can be found flapping its speckled wings on Burdock any time from spring through to autumn. Apparently, the larvae make a gall, so I’m going to revisit this particular plant to check for those.
