DIGGER WASP
Sphex rufocinctus
This wasp digs some 10 cm deep burrow in the ground. With its legs, it sweeps away the dug out soil, to prevent the heap of soil betraying its nest to the predators.
Then it catches several grasshoppers or crickets, which it paralyses by squirting poison it in their nervous system. Thereupon it drags them in its underground nest. On the last prey it lays an egg and closes the nest carefully with soil, making it imperceptible. The hatched larva grows on the prepared food and leaves the nest only in the ensuing year.
