They are found worldwide. Females lay their eggs on foliage. The eggs are elongated and white and are at the end of a stiff thread. They hatch in the early cool spring and crawl down the stalks of plants. This gives them a head start on those aphids before they can get a foothold in your garden. The larvae look like small alligators with bits of fluff on their sides. Adults live for approximately 5 weeks and then lay their eggs and die. There is usually at least 2 generations a year.
