Studies on the flies occurring from the excrement of pasturing cattle and other herbivorous animals : 3. On the 3rd stage larvae of the genus Morellia R.-D. from Japan (Diptera : Muscidae)

Abstract

The 3rd stage larvae of 4 species belonging to the genus Morellia R.-D. from Japan are described and figured. Those are M. saishuensis Ouchi, M. hortensia (Wiedemann), M. hortorum (Fallen), and M. aenescens R.-D. External characters of those species are similar each other, however, posterior spiracles of saishuensis, and shape and size of anterodorsol spines in each species are characteristic. Those are most useful characters for identification of Morellia-larvae. The larva of M. saishuensis is newly described in this paper.
