The insects chosen for this Vignette are such as afford examples either of
longevity, of brevity of existence, or of great disproportions in the
length of its several stages. The Brown Weevil (Curculio), a feeder on
decayed wood, at the right hand corner, gives an instance of longevity,
contrasted by the brief duration of the Ephemeral Day-fly (Baetes),
which rises upwards on the left. In this Ephemera there are two instead
of (as in E. vulgata) three filaments, proceeding from the extremity of
the body. On the right, is a common Cockchafer (Melolontha vulgaris);
another of the same species, just arrived at maturity, is pushing ap-
wards from the grass; while a third, yet in its stage of larva, is

The examples of slow and swift-footed beetles here given, are the Oil Beetle
(Proscarabæus vulgaris), laboriously creeping up, and the Tiger Beetle
(Cicindela campestris), rapidly descending the sandy bank. Below, is a
fast walker, almost runner, among hairy caterpillars, and above, on a
lime-tree twig, sits the stately larva of the Lime Hawk Moth (Smerinthus
Tilia), like the rest of its Sphinx-like brethren, slow-footed and averse to
motion. The two flies are of a flower-resorting species, called vibrating
(Scioptera vibrans), which are distinguished by red heads, scarlet eyes,
black-tipped wings, and that quivering or vibrating motion to which
they owe their name
