| Only the wings of the male
cricket have sound-producing attachments, and the males
have them only when their wings are fully developed at
the age of maturity. The young cricket has no wings. Since
crickets produce a characteristic sound, it is natural to
suppose that both males and females are able to hear it.
On the lower part of the fore legs of both sexes is found
a little drum-like surface, which serves as the tympanum
of an ear. The sound-producing organ and the ear of the
katydids, which rank next to the crickets in their
singing ability, are some-what similar in structure and
location.
The
sound mad by crickets is, of course, not a true song, but
a mechanical production, as are all of the sounds
produced by insects. The object of the chirping or
stridulating is somewhat conjectural. It may be a
love-song, mating-call, or an expression of some other
emotion. The fact that the crickets are able to sing only
when they are full-grown and capable of mating would seem
to suggest that their chirping is a love-song.
