INSECT WAYS
"Some day ere I grow too old to think I trust to be
able to throw away all pursuits, save natural history,
and to die with my mind full of God's facts instead
of men's lies."--CHARLES KINGSLEY.
August 2, 1909.
A lanky grasshopper with keeled back and pointed prow flew before me,
settling on a leaf of blady grass, at once became fidgety and restless;
flew to another blade and was similarly uneasy. It was bluff in colour
with a narrow longitudinal streak of fawn, while the blades of grass
whereon it rested momentarily were green. Each time it settled it
adjusted itself to the blade of grass, became conscious of discomfort or
apprehensive of danger, and sought another. Presently it settled on a
yellowing leaf, the tints of which exactly corresponded with its own. The
longitudinal streak became absorbed in the midrib of the blade, and the
insect rested secure in its invisibility. The event demonstrated the
purpose of its previous restlessness.
CARNIVOROUS WASPS
October 6, 1909.
This morning the soda siphon (which had not been used for a couple of
days) refused duty, owing to a plug of terra-cotta-coloured clay.
Upon the spout being probed the gush of gas expelled a quantity of
clay and thirty-five small spiders, representative of about six
different species. The spout had been converted into a nursery and
larder by a carnivorous wasp, for in addition to the moribund spiders
stored for the sustenance of future grubs were several unhatched
eggs. Such wasps are exceedingly common, some building "nests" as
large as a tea-cup, the last compartment being fitted with an
elegantly fashioned funnel, the purpose of which is not obvious.
If these nests are broken up, after the hatching out, the grubs are
found-several in each compartment--feasting on the comatose spiders
or caterpillars stored for their refreshment. Others of the species build
a series of nests, detached or semi-detached, and shaped in resemblance
to Greek amphora. Another species selects hollows in wood in which the
eggs and insects are scaled. The larger wasps are not fearful of
attacking so-called tarantulas, one sting rendering them paralytic.
