It seems as though the creature recognises the impossibility of renewing its store of liquid, and so economises the little it possesses, using only just so much as is necessary in order to escape as quickly as possible from surroundings which are strange to its inherited instincts.

This parsimony is so well judged that the insect gains the surface at the end of twelve days.
The gate of issue is opened and left gaping, like a hole made with an augur.

For some little time the larva wanders about the neighbourhood of its burrow, seeking an eyrie on some low-growing bush or tuft of thyme, on a stem of grass or grain, or the twig of a shrub.

Once found, it climbs and firmly clasps its support, the head upwards, while the talons of the fore feet close with an unyielding grip.

The other claws, if the direction of the twig is convenient, assist in supporting it; otherwise the claws of the two fore legs will suffice.
