Predaceous diving beetles are highly adapted for aquatic life, and with more than 4000 species, is the most diverse water beetle family (Figures 12 and 13). It is in the family Dytiscidae (See BugGuide) and we cannot provide you with an exact species name, but perhaps Markikavana will write in with an identification. It may look like it only has two front legs, but its other 4 legs are underneath it, out of sight. Diving beetles have a streamlined shape, a pair of thin antennae and three pairs of legs. What We Can Do - Like all aquatic insects, predaceous diving beetles depend on clean water to live.

Life Cycle: Adults and larvae are found in water. The meaning is able to dive. Predaceous diving beetle life history stages affect interactions with shared 2 mosquito prey 3 4 5 C. Bofill1,3 and D.AYee1,2 6 7 1Department of Biological Sciences, University of Southern Mississippi, Hattiesburg, 8 Mississippi, 39460, U.S.A., 601-266-4927 All predaceous water beetle larvae and adults are predaceous, principally eating invertebrates, probably enchytraeid worms and aquatic larvae of flies (Diptera). The largest predaceous diving beetles are most easily captured with baited minnow traps, but be sure to keep part of the trap above the water so that beetles can breathe. Life cycle: Eggs are laid on the surfaces of submerged aquatic plants. Status - Abundant. Giant Water Bugs. The latter surface for air head first and have a ridge or keel on the underside that runs down the thorax and extends into a point. Uses. They have four stages in their life cycle: egg - larva - pupa - adult. Young. If they can breathe, they will drown in the traps. Life Span. Black light traps are commonly used by entomologists and work well for collecting some beetles, but aren’t required. Predacious Diving Beetles are included in a family of beetles, Dytiscidae, that are adjusted to living in water at any phase of its life cycle. The disappearance of wetlands and the pollution of rivers and streams are a potential threat to this and all aquatic insects. Seasonal Changes. Mating occurs from spring to autumn. Voice. In Greek, the term means “able to dive”. Diving beetles are insects. However; you can see variations of length among the species of diving beetles. Though their family is likely to have around 4000 categories in about 160 classes, it has not been completely documented since 1920. Their back legs have a thick fringe of swimming hairs. Despite their diversity and abundance, little is known of life histories. Check other interesting facts about diving beetles below: ...
