Macrophya militaris (Klug, 1817)

( Figs. 5 , 11 )

Material examined. Bohemia centr.: Lipovka NR (5854), 19.vii.2009, 3 larvae on Fragaria vesca ,; Karlštejn NNR (6051), 23.vii.2008, 2 larvae on Fragaria viridis .

Notes on identification. The larva was described by Zirngiebel (1940) and again by Lorenz & Kraus (1957). The last instar larva is easily distinguished from the similar larvae of both M. montana and M. rufipes , by the lunular parietal macula, which is not confluent with the black neck spot, and by the enlarged longitudinal dark stripe on the dorsum.

Discussion. Taeger et al. (1998) listed Rosa and Origanum as food plants. Zirngiebl (1940) proved Origanum to be a suitable oviposition site, but larvae in this study did not accept it. Therefore Origanum should be excluded from the food plant list. I have collected the larvae on Fragaria vesca (new record) and F. viridis (new record), in captivity they also accepted Potentilla reptans and various Rubus species.
