Contarinia cucubali Kieffer, 1909
The topmost two leaves are abnormally short and broad, and folded towards each other, their margins touching. In the resulting cavity several white, 2 mm long larvae, that can jump. Hibernation in the soil; probably univoltine. Spatula of the larva hyaline except for the yellow apical part with two obtuse lobes, almost as long as broad, that are separated by a wide concave incision.
Caryophyllaceae, narrowly monophagous
