grubling

When she has finished her hole, the inside of which she smooths with great care, in order that it may be comfortable for her little grublings, she lays an egg at the bottom, and then goes to work to provide a supply of food for the future wasp.

As they are fed up in this way several times a day the ugly grublings soon begin to grow in breadth and stature, until they suddenly burst forth into full-blown wasps, and immediately begin to relieve their mother of her multitudinous duties.
