Bohemia bor.: Czech Switzerland NP, Růžovský vrch NR (5151), 21.vii.2010 , 3 larvae on Knautia arvensis . Bohemia or.: Orlické hory PLA: Nebeská Rybná (5864), 4.viii.2010 , 15 larvae on Knautia arvensis ; Kačerov NR (5764), 5.viii.2010 , 4 larvae on Knautia arvensis . Description of the last instar larva. Body length: 12–14 mm ; head pale brownish, body pale green, annulet 2 with large, annulet 5 with small rounded black spot above the spiracular line, subspiracular and suprapedal lobe with more or less developed dark transverse spot; coxae with dark basal spots. Head with short pubescence, clypeus with four setae, labrum with six setae, mandibles with two setae, stipes with one seta, palpifer with three setae, the second article of maxillary palpus with one seta; abdominal segments with seven smooth annulets; annulets 2, 4, 7 with 6-8 scattered tiny setae, annulet 2 with 2–4, annulet 4 with 2–3 small conical pale glandubae; spiracles yellow, the first postspiracular lobe with one glanduba and 4–6 tiny setae, the second postspiracular lobe with three glandubae and 4–6 tiny setae, the subspiracular lobe with 10–13 tiny setae and one glanduba, surpedal lobe with one glanduba and 11–13 tiny setae; the exterior part of proleg bare, the interior side with 6–7 setae at base. Notes on identification of larva. The larva of M. recognata is very similar to that of M. erythrocnema but differs in its ecology. The former prefers mesic meadows at higher altitudes. Bionomics. Habitat: mesic hay meadows in foothills and submontane zone. Univoltine. Flight period from mid May to the beginning of July; larval period from mid June to mid August. Host plant: Knautia arvensis . The larvae rest on the underside of leaves. The infested plants are traced by the large holes on the leaves. Larval development is quick, taking about one month; eonymphe rests for a longer time (up to six weeks) coiled on the underside of the leaves of various surrounding vegetation before burrowing into the soil for hibernation diapause.
