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.Continue Reading
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
Depending on the species, insects may reproduce either sexually or asexually. Sexual reproduction requires one egg from a female and a sperm from a male. The sperm fertilizes the egg, which resides in the female through its term to hatch insects when the growth and development stage is complete.Full Answer >
Some snakes reproduce by laying eggs while other species give birth to live young. How snakes reproduce depends on the species and also the location. In cooler regions of the world, snakes reproduce only in spring and summer, while in warm regions they may reproduce all year long.Full Answer >
Platyhelminthes, also known as flatworms, are hermaphrodites, meaning individuals of the species produce both sperm and eggs. These are released from the platyhelminthes where they become cross-fertilized by other platyhelminthes. Two types of platyhelminthes, trematoda and cestoda, lay eggs constantly. The turbellarian class has a seasonal cycle. Turbellaria also reproduce asexually by dividing. Turbellaria are the only class able to regenerate body parts.Full Answer >
All species of crabs reproduce by laying eggs, but the females and males still need to mate to fertilize the eggs. During mating, the male crab carries the female on his back for up to two weeks, after which the female stores the male's sperm in sacs on her abdomen.Full Answer >
