They live in ponds, shallow lake areas, and still areas of rivers and streams. Unlike ground beetles, the head of tiger beetles are wider than their thorax. Notes - Water scavenger beetle larvae can often be difficult to identify below the Family level. Stoneflies are so named because the nymphs often live under stones in streams or rivers.
