Sample text

Not unexpectedly, none of the oceanic water striders has wings. They would probably be of little or no use, not worth the energy it takes to develop and maintain them. These insects have no need to disperse between separate bodies of water as 42 Where They Live do the freshwater species. If one bit of ocean surface is more accommodating to them than another, then there is always a good chance that they will be carried there by the wind, the waves, and the tide. Because they have gradual metamorphosis, as do all the other true bugs, the nymphs are as capable of riding the waves as are the adults, and of course there is no immobile and vulnerable pupal stage.

They feed on algae and other plants, and are often found in masses of vegetation. Almost all the herbivorous leaf beetles (family Chrysomelidae) are land dwellers; a mere handful, species of Donacia and Haemonia, feed on aquatic plants and are unusual because the larvae tap hollow spaces in these plants to obtain air. They pupate under water in airtight silken cocoons attached to plants and filled with air from the plant. Caddisflies (Order Trichoptera) Caddisfly larvae are aquatic and live in ponds, lakes, rivers, or brooks, except for a few land-dwelling species in Europe and Oregon.

A few of the Hydrophilidae, water scavenger beetles, live in dung, but the great majority are aquatic. Adults, competent swimmers, are mainly scavengers, but most larvae are predators. A few riffle beetles (family Elmidae) live in ponds or lakes, but most of these tiny plant eaters crawl on the bottom or on plants in cold, fast-flowing streams. The behavior of the beetles of the family Haliplidae is described by their common name, crawling water beetles. They feed on algae and other plants, and are often found in masses of vegetation.
