Lipara sp., Chloropidae. Image unsufficient to identify the two following species: L. pullitarsis Doskočil & Chvála, 1971 and L. rufitarsis Loew, 1858 are very similar, after the literature only separable after the male (and also female) genitalia. Unpublished observation by M. von Tschirnhaus: L. rufitarsis: the 3rd tarsal segment of the fore- and mid-leg is longer than wide and longer than the 4th segment; the tips of the femora are wider yellow, especially dorsally, the veins of the wing base are yellowish (not brownish), the keel between the antennae is not wider than the diameter of a palpus, the pubescence of the eyes is whitish-grey (not dark). The larvae of both species produce galls in reed stems (Phragmites australis) which are not lignified and, thus, suffer heavy attack during the winter by the blue tit, which is feeding on the larvae.
