Previously restricted to a few sites in the UK it is now a common and very abundant species. Adults feed on a wide range of plant families and especially like oxeye daisy (Leucanthemum vulgare) and umbellifers (Apiaceae) which they can often be seen on at the garden. Males have large swollen back legs, which gives the species its name, while the females do not! Adults can be seen in great numbers but the larvae are quite difficult to find as they are well concealed in dry stems of various plants. You’re doing well if you can find one!
