F the box, as Megachile sericans does with her paliurus. The lilac-lover
disdains them absolutely. For what reason? I fancy that she finds them
too stiff. Would she think differently if the lilac-bush were not there?
Perhaps so. In short, apart from the questions of texture and proximity
to the nest, the Megachile's choice, it seems to me, must depend upon
whether a particular shrub is plentiful or not. This would explain the
lavish use of the vine, an object of widespread cultivation, and of the
hawthorn and the wild briar, which form part of all our hedges. As these
are to be found everywhere, the fact that the different Leaf-cutters
make use of them is no reflection upon a host of equivalents varying
according to the locality. If we had to believe what people tell us
about the effects of heredity, which is said to hand down from
generation to generation, ever more firmly established, the individual
habits of those who come before, the Megachiles of these parts,
experienced in the local flora by the long training of the centuries,
but complete novices in the presence of plants which their race
encounters for the first time, ought to refuse as unusual and suspicious
any exotic leaves, especially when they have at hand plenty of the
leaves made familiar by hereditary custom. The question was deserving of
separate study. Two subjects of my observations, the Hare-footed and the
Silvery Leaf-cutter, both of them inmates of my open-air laboratory,
gave me a definite answer. Knowing the points frequented by the two
Megachiles, I planted in their work-yard, overgrown with briar and
lilac, two outlandish plants which seemed to me to fulfil the required
conditions of supplenes
