She inspects the
peas, still on the vine, and enclosed in their pods; she auscultates
them with her antennae; she discovers, hidden under the general
envelope, the weak points in the epidermic covering of the peas. Then,
applying her oviscapt, she thrusts it through the side of the pod and
perforates the circular trap-door. However far withdrawn into the centre
of the pea, the Bruchus, whether larvae or nymph, is reached by the long
oviduct. It receives an egg in its tender flesh, and the thing is done.
Without possibility of defence, since it is by now a somnolent grub or a
helpless pupa, the embryo weevil is eaten until nothing but skin
remains. What a pity that we cannot at will assist the multiplication of
this eager exterminator! Alas! our assistants have got us in a vicious
circle, for if we wished to obtain the help of any great number of
Chalcidians we should be obliged in the first place to breed a
multiplicity of Bruchidae.
