Classification:
Chrysolina haemoptera belongs to the subfamily Chrysomelinae, tribe Doryphorini.
Distribution:
Europe, east to Caucasus; Turkey; Iran.
Habitat:
Open, rather dry grassland (meadows, pastures, ruderal areas, nutrient-poor grassland, coastal dunes).
Description:
Length 5 - 9 mm; body, legs and antennae blackish blue; antennal base reddish brown; pronotum finely dotted, straight from base to end, conically constricted and without lateral bulge; wing covers coarsely dotted and with deeply depressed seam strip at tip; dots on wing covers arranged in rows in places.
Biology:
The Plantain Leaf Beetle Chrysolina haemoptera forms one generation per year. The beetles are mainly nocturnal and hide during the day. There are both long- and short-winged forms.
The adults can be found from the beginning of June to July and after a summer diapause controlled by the length of the day from the end of August to October. Egg deposition begins in autumn and continues after wintering in the following spring to April. A female lays up to 200 eggs. These are laid at the base of the larvae' food plants. Host plants of the larvae are different plantain species (Plantago, Plantaginaceae). The larvae hatch 20 - 30 days after oviposition. The larvae hatched in autumn, overwinter with the adults of the previous generation and pupate in the soil in spring. The imagines of the new generation hatch from the end of May to the beginning of June.
When breeding under laboratory conditions, the pupation and hatching of the new generation took place already in October.
Natural Enemies:
The larvae of the tachinid fly Polycheta unicolor (Diptera: Tachinidae) are endoparasites of the imagines of Chrysolina haemoptera.
The larvae of the fairy wasp (or fairyfly) Anaphes chrysomelae (Hymenoptera: Mymaridae) develop as endoparasitoids in the eggs of Chrysolina haemoptera.
