Lacewing / Antlion - Red Lacewing (Dysochrysa furcata) family Chrysopidae

Sometimes called 'doodlebugs' - This antlion was not easy to get a photograph of as they disappear so easily once you start digging into their cone-shaped nest and look like this:

I am sure you have seen them in your garden.
The sides are built at a 45 degree angle and once the ant falls in, he cannot get out again. The larvae is extremely small, about 2-3mm.
Lacewing larvae are carnivorous and differ in appearance and habit, but all have elongated mouthparts modified for sucking out the fluids of their prey.

Their anus is sealed so that waste products of their diet can be stored until excreted as a white pellet after emergence.

They spin a spherical cocoon for pupation.
