As to the beetles, we
have quite well-observed facts of mutual help amidst the burying
beetles (Necrophorus). They must have some decaying organic
matter to lay their eggs in, and thus to provide their larvae
with food; but that matter must not decay very rapidly. So they
are wont to bury in the ground the corpses of all kinds of small
animals which they occasionally find in their rambles. As a rule,
they live an isolated life, but when one of them has discovered
the corpse of a mouse or of a bird, which it hardly could manage
to bury itself, it calls four, six, or ten other beetles to
perform the operation with united efforts; if necessary, they
transport the corpse to a suitable soft ground; and they bury it
in a very considerate way, without quarrelling as to which of
them will enjoy the privilege of laying its eggs in the buried
corpse. And when Gleditsch attached a dead bird to a cross made
out of two sticks, or suspended a toad to a stick planted in the
soil, the little beetles would in the same friendly way combine
their intelligences to overcome the artifice of Man. The same
combination of efforts has been noticed among the dung-beetles
