In Connecticut his shrill note rings everywhere along the road- sides, on warm bright afternoons of September and October, as the player sits on leaf or twig fully exposed to the sun. At this season also, both the snowy and the narrow-winged sing by day but usually later in the after- noon and generally from more concealed places. We should naturally like to know why these little creatures are such persistent singers and of what use their music is to them. Do the males really sing to charm and attract the females as is usually pre- sumed? We do not know; but sometimes when a male is sing- ing, a female approaches him from behind, noses about on his back, and soon finds there a deep basinlike cavity situated just behind the bases of the elevated wings. This basin contains a clear liquid which the female proceeds to lap up very eagerly, [68] Fig. 40.
