The Tobacco-worm is a caterpillar of the size and figure of a silk-worm. It is of a fine sea-green colour, with rings of a silver colour; on its rump it has a sting near a quarter of an inch long. These insects quickly do a great deal of mischief, therefore care is taken every day, while the tobacco is rising, to pick them off and kill them.
In summer Caterpillars are sometimes found upon the plants, but these insects are very rare in the colony. Glow-worms are here the same as in France.
Butterflies are not near so common as in France; the consequence of there being fewer caterpillars; but they are of incomparable beauty, and have the most brilliant colours. In the meadows are to be seen black grasshoppers, which almost always walk, rarely leap, and still seldomer fly. They are about the size of a finger or thum, and their head is shaped somewhat like that of a horse. Their four small wings are of a most beautiful purple. Cats are very fond of grasshoppers.
The Bees of Louisiana lodge in the earth, to secure their honey from the ravages of the bears. Some few indeed build their combs in the trunks of trees, as in Europe; but by far the greatest number in the earth in the lofty forests, where the bears seldom go.
The Flies are of two kinds, one a yellowish brown, as in France, and the other black.
The Wasps in this country take up their abode near the houses where they smell victuals. Several French settlers endeavored to root them out of their neighbourhood; but I acted otherwise; for reflecting, that no flies are to be seen where the wasps frequent, I invited them by hanging up a piece of flesh in the air.
The quick-stinger is a long and yellowish fly, and it receives its name from its stinging the moment it lights. The common flies of France are very common also in Louisiana.
The Cantharides, or Spanish flies, are very numerous, and larger than in Europe; they are of such an acid nature, that if they but slightly touch the skin as they pass, a pretty large blister instantly rises. These flies live upon the leaves of the oak.
The Green-flies appear only every other year, and the natives superstitiously look upon their appearance as a presage of a good crop. It is a pity that the cattle are so greatly molested by them, that they cannot remain in the fields; for they are extremely beautiful and twice as large as bees.
Fire flies are very common; when the night is serene they are so very numerous, that if the light they dart out were constant, one might see as clearly as in fine moonshine.
