Full Answer

Adult fleas live on the host animal, drinking blood from the host animal to survive. Fleas reproduce by laying large numbers of eggs. Some of the eggs remain on the host animal, and others fall off into the environment. The eggs hatch into worm-like larvae that eventually turn into adult fleas. If a flea developed in the environment instead of on a host animal, it searches for a host animal to inhabit. Most flea species seem to prefer living on rodents and similar animals because they maintain permanent dens, which are ideal environments for flea larval development.

  • Q:

    How do fleas reproduce?

    A:

    The way fleas reproduce depends on their species and environmental conditions, states "Flea Control: How to Get Rid of Fleas Naturally." For example, the water flea reproduces asexually under normal conditions. These fleas only produce females until abnormal conditions, such as overcrowding or a limited food supply, cause them to asexually produce only males. The male fleas then mate with the females to continue reproduction until conditions change again.

    Where do dragonflies live?

    A:

    Dragonflies live around freshwater and lay eggs in freshwater, usually on plants. Dragonfly larvae have gills and live underwater. When a larva is mature, it climbs out of the water and molts, following which an adult dragonfly emerges from the shed skin. Adult dragonflies live around water as well but are capable of flying long distances in search of food and mates.
