IMAGINES O F O T H E R INSECTS A N D A F E W ARTIIROPODA Aphis hederce is dark and inconspicuous; aphides are generally inconspicuous but probably also, in some cases, protected in other ways (taste or smell). The species made use of was inconspicuous; but many possess warning-colours. The species was, however, evil-smelling, like the brilliant ones. Musca domestioa and M, vomitoria chiefly employed; but also any other Muscidae which could be found. The appearance, and especially the rapid flight and readiness with which they are disturbed, are strongly protective. Larvae and pupae also made use of: both concealed. Probably the commonest species. Although somewhat less well-concealed than many species of Musca, many of the species of these genera are even stronger on the wing. The common male is black and inconspicuous: the much less common female orange-coloured and easily seen; both fly readily when disturbed. The dark colour and habits of concealment are certainly protective. Nocturnal habits also. As above, the species being similar in habits and appearance, only much smaller. Nocturnal habits. |
