Their works under ground are no less extraordinary: Azara has described with his usual minuteness the various species which he fell in with. There is one amongst others which is winged, and the swarms of which are so prodigious, that he says he rode for three leagues continuously through one of them. This was in about the latitude of Santa Fé, where they particularly abound, and where the people catch them and eat them. The hind parts it seems are very fat, and they fry them into a sort of paste or omelette, or, mixed up with sugar, make sweetmeats of them.
They are a sad pest to the agriculturist and a great nuisance when they get inside the houses. At Buenos Ayres they are very troublesome: I tried myself every means in vain to get rid of them; their ingenuity always baffled us; no contrivance could keep anything in the shape of sweetmeats or dried fruits or such things out of their clutches; and as to the quantity of sugar they would carry off in a very short time, it was incredible: we thought to escape them by placing our stores upon tables, the legs of which were surrounded by water, but they threw straws and sticks into the water, and so made themselves bridges to cross by. If we hung them from the ceiling they climbed the walls and descended by the ropes which suspended them. In our garden they committed terrible depredations; and in the summer-season it was always necessary to keep a couple of men constantly employed for the sole purpose of destroying their nests. We observed that they could not exist in the sun; so that, if a basin of sugar were half filled with them, as was constantly the case, by putting it into the sun it was presently cleared of every one of them.
The Jesuit father Guevara, in his account of Paraguay, speaks of a species not noticed by Azara, found about Villa Rica, which deposits upon certain plants small globules of white wax, which the inhabitants collect to make candles of. The utility they are of in this respect, he says, in some measure compensates for the damage they do to the husbandman. Against their depredations, St. Simon and St. Jude, and St. Bonifacio[53], have been by turns elected in due form to be the special guardians and protectors of all good Catholics.
