Insects that lay eggs are called orthopterans, which consist of common species such as praying mantis, cockroaches, crickets and grasshoppers. Although these insects all lay eggs, they have different methods of carrying out the egg laying process. All egg-producing insects have distinct methods of carrying, hatching and raising their young.Know More
In addition to variation in egg-laying habits among species, there is also diversity in habits between members of the same species. In the cockroach family, for instance, females in only one family (Blaberidae) have egg cases that lack clear definition and structure. In some cockroach families, females carry egg sacs called oothecae outside their bodies until it is time for the eggs to emerge, while other females deposit their egg cases in nests several days before the eggs emerge.
The eggs produced by the different egg-laying insects vary in size, color and appearance. Eggs of the walking stick species, which includes praying mantis, look like small seeds and are usually dispersed by females loosely on the ground before hatching. Crickets, in contrast, lay their eggs within soils or plant materials and arrange their eggs in rows prior to hatching. Grasshoppers lay their eggs in soil or deposit them in dead wood or grass clumps. Grasshoppers produce large volumes of eggs, which are housed in protective sacs before hatching.Learn more about Animal Reproduction
Fish lay a large number of eggs because only a few of them, out of thousands, will be fertilized and produce a fish. This is because they are fertilized outside of the body and are highly sensitive to temperature changes and external factors.Full Answer >

The buffalo and the cowbird have a symbiotic relationship, where the cowbirds eat the insects kicked up by the buffalo as they feed on grass. The cowbirds follow the buffalo and other cattle in search of the insects and historically kept to American grasslands. In modern times, cowbirds are considered parasitic birds and can be found throughout the United States.Full Answer >
