The Spaniard fly and free-mason fly are both of the wasp kind, but they differ from each other in size, shape, and also in the substance and curious manner of making their nests. The first is of the shape of a small bee, and builds its nest of a waxy matter, in the form of a small flat button full of holes, which it suspends by a silky ligament to the cielings of houses, or to the boughs of trees, where it has the benefit of the wind to vibrate to and fro.
The free-mason fly is exactly of the shape, size, and colour of a wasp, and builds its nest of mud, in the shape of organ barrels. It is curious to see these little creatures at work, they shew so much art and industry, some of them fetching the mud in their mouths, while others are forming their small cones, or filling them up when finished with numbers of various-coloured small spiders, which they also bring in their mouths, for food to their young when hatched. That which is further remarkable of these flies is, that it appears they qualify the spiders, by some means, for remaining a long time in as perfect a state as the first day they were immured in their cells; I have seen spiders, so immured for several weeks, as whole and perfect in size, shape, and colour, as when alive.
There is another species of these flies, called galley wasps, which is double the size and of a bright light-blue colour. These have very long stings, which are plainly to be seen when they are flying, with which they wound very severely, causing the blood to spout out, as from the prick of a lancet.
The sting of these flies is very painful, and persons have been thrown into fevers by being stung severely by them; but they are seldom offensive, unless disturbed.
The wood-horse, called by the negroes the fairy-horse, is a very singular insect. Its head is like that of a grasshopper, it has two horns, considerably longer than its own body, which is about three inches, and of one continued thickness, like a large caterpillar. It has six legs, which are raised and doubled above its body, like the springing legs of a grasshopper, but they have not the same power, serving it only to walk with, which it does very fast. It has no wings, is of a deep green colour, and is perfectly harmless.
The vegetable fly is a remarkable insect. It is of the appearance and size of a small cockchafer, and buries itself in the ground, where it dies, and from its body springs up a small plant, which resembles a coffee-tree plant, only its leaves are much smaller. The plant which springs from this insect is often overlooked, from the supposition people have of its being no other than a coffee plant; but on examining it properly, the difference is easily distinguished, from the head, body, and feet of the insect appearing at the root, as perfect as when alive.
In the woods of Dominica are vast swarms of bees, which hive in the trees, and produce great quantities of wax and honey; both of which are equal in goodness to any of those articles to be had in Europe.
The musquitoes and sand flies are not so numerous, or so troublesome in this country, as they are in most parts of the West Indies, owing to there being but few spots of stagnated water, which breeds them.
The musquito is a species of the gnat kind, but rather smaller than the common gnat in England. The sand fly is not much larger than the head of a large pin, but is a very tormenting little insect in some islands, particularly to persons newly arrived from Europe.
