Summary:

CD asks about HD’s observation of sexual call of Coleoptera.

Also comments on statements by collectors that they breed more females than males from caterpillars. CD had thought this might be accounted for by the collection of largest and finest caterpillars, but Alexander Wallace says the collectors take large and small equally. Does HD agree with Wallace?
