寄生蜂的一种,无害,中文好像叫 蜾蠃
Nesting habit and prey: Eumenes is a solitary wasp. Her common name, potter wasp, describes her habit of building a small mud pot which she provisions for her young. She does not gather mud, but rather carries water in her mouth to dry dirt and makes her own mud. Again, using her mandibles, she makes little mud balls and transports them back to her nest site. She makes several hundred trips, and takes up to two hours, to build one pot. When the pot is finished, she inserts her bulbous abdomen into the pot and lays one egg. Then she hunts for caterpillars and bug nymphs, stinging them, paralyzing, but not killing them. She brings them back to the nest pot, stuffs them in, and seals the nest. Then she goes off to start another nest. |
