Day As Insects Struggle:
In the wild, crayfish feed on small fish, worms, aquatic insects, and decomposing organic matter. Give bits of raw or cooked meat, chopped raw fish, earthworms, water insects, prepared fish food, and soybean meal; do not overfeed; crayfish tend to overeat. Prevent pollution at all times; clean out leftover bits of food soon after feeding.
INSECTS, which make up the largest group of animals in the ani¬mal kingdom and the largest class in the phylum Arthropoda, occur in untold numbers throughout the world. This is, in reality, the age of insects as today as insects struggle they are the most successful creatures in the common struggle for existence. Insects not only make up the largest class in the animal kingdom but they present man with his most difficult problems. A great many insects are beneficial to man but the majority are harmful.Insects vary greatly in size and shape. The smallest insects are the tiny fairy flies, which are less than Ymo of an inch (0.025 mm) long and develop inside the eggs of other insects. The largest living insects are the stick insects,which may be 10 inches (25.4 cm) long, and the giant moths, which have a wingspan of 10 inches. Some insects, such as the walking stick, have greatly elongated bodies. Other insects, such as many of the beetles, have flattened and rounded bodies.
See Also Mature Insects Emerge:
The life history of May or June beetles differs in that it takes two to four years, but most commonly three, from the time the eggs are laid until the mature insects emerge. During the last year of the cycle they do not feed, but in earlier years they eat as voraciously as the other beetle grubs.Wings. Most adult insects have two pairs of wings, which arise as outgrowths of the cuticle from the second and third segments of the thorax. The earliest insects had no wings, and some of their direct descendants never acquired them. Most living insects, however, had winged an¬cestors, but some of them subsequently lost their power of flight and have reduced, nonfunctional wings or no wings at all. Some species, including the deer keds, have wings when they first emerge as adults, but break their wings off near the base after their first mating flight.

There are nearly 1 million different species of insects, more than the combined number of all other animal and plant species. On the North American continent alone there are more than 80,000 dif¬ferent species of insects. Insects are also the most widespread of all animals, inhabiting practically every type of environment, from the edges of frozen ice fields and glaciers to hot tropical forests. They in¬habit swamps, deserts, lakes, high mountaintops, and seashores. Many insects are carried high into the air, and one or two species are found in the open ocean. Some insects live in or on other animals, including other insects.
