George A. King, ../../ (1913)
“ These little jugs are made of wet clay which the parent wasp gathers for the purpose, and, when thoroughly dry, are hard and enduring. When a jug is finished, it is filled with small spiders or caterpillars, that are first made dormant by the sting of the wasp, but not killed, and in each jug an egg is laid, after which the opening is sealed with a little clay cork. ”
