Myrmeleonidæ—Ant-lions.
When children meet with the funnel-shaped pitfalls of the larva of the Ant-lion, Myrmeleon formicales, they are wont to put their heads close to the ground and softly sing ooloo-ooloo-ooloo, till the larva, mistaking the sound for that of a fly escaping his trap, throws up a shower of sand to bring its supposed victim down again.
Ant-lions are held in great esteem in many sections of our country, so much so that they are not suffered to be in any way injured.
