For a long time I have desired my relation to look out for these birds in Andalusia, and now he writes me word that, for the first time, he saw one dead in the market on the 3rd September.
When the œdicnemus flies it stretches out its legs straight behind, like a heron.

LETTER XXXIV.
Selborne, March 30th, 1771.
Dear Sir,—There is an insect with us, especially on chalky districts, which is very troublesome and teasing all the latter end of the summer, getting into people’s skins, especially those of women and children, and raising tumours which itch intolerably. This animal (which we call a harvest bug) is very minute, scarce discernible to the naked eye, of a bright scarlet colour, and of the genus of Acarus. They are to be met with in gardens on kidney-beans, or any legumens, but prevail only in the hot months of summer. Warreners, as some have assured me, are much infested by them on chalky downs, where these insects swarm sometimes
to so infinite a degree as to discolour their nets, and to give them a reddish cast, while the men are so bitten as to be thrown into fevers.
There is a small, long, shining fly in these parts very troublesome to the housewife, by getting into the chimneys, and laying its eggs in the bacon while it is drying; these eggs produce maggots called jumpers, which, harbouring in the gammons and best parts of the hogs, eat down to the bone, and make great waste. This fly I suspect to be a variety of the musca putris of Linnæus; it is to be seen in the summer in farm-kitchens on the bacon-racks and about the mantel-pieces, and on the ceilings.
The insect that infests turnips and many crops in the garden (destroying often whole fields while in their seedling leaves) is an animal that wants to be better known. The country people here call it the turnip-fly and black-dolphin; but I know it to be one of the coleoptera; the “chrysomela oleracea, saltatoria, femoribus posticis crassissimis.” In very hot summers they abound to an amazing degree, and, as you walk in a field or in a garden, make a pattering like rain, by jumping on the leaves of the turnips or cabbages.
There is an oestrus, known in these parts to every ploughboy, which, because it is omitted by Linnæus, is also passed over by late writers; and that is the curvicauda of old Mouset, mentioned by Derham in his
