An adult dragonfly may live for several months after leaving its water-born nymph phase. However, if accounting for the entirety of the insect's life cycle from hatching until death, the life of a dragonfly could span several years.Continue Reading
A dragonfly nymph lives underwater and hunts other invertebrates for anywhere from six months to four years. During this time, the nymph molts or sheds its skin up to 15 times, depending on the species. Once the nymph has completed its growth process, it swims to the surface and anchors itself to a stem or root before undergoing metamorphosis. Dragonflies are different from other insects, like moths and butterflies, in that they do not require a cocoon or pupa in order to change from a larvae into an adult.
Once the winged adult dragonfly has emerged, it needs to sit and wait for its wings to dry. This phase of the life cycle is known as a "teneral," which is Latin for "tender, soft or delicate." After a few hours, the adult dragonfly will take to the air where it will prey on other winged insects. The temperature and weather greatly affect how long the dragonfly lives at this stage in its life. If the weather is warm and the dragonfly is able to avoid predators it can live up to six months. However, if the temperature is cold then adults may only live a few weeks.Learn more about Butterflies & Moths
According to HowStuffWorks, the time required for a caterpillar to pupate (change into an adult butterfly or moth) averages about two weeks. However, the exact time that the caterpillar stays in the cocoon varies by species.Full Answer >
The adult hummingbird moth feeds on nectar from flowers, preferring plants such as thistles, red clover, wild roses, Japanese honeysuckle, bee balm, lilac, blackberry, cherry and blueberry. Gardeners can grow these plants in their yards to attract hummingbird moths ranging nearby. Their habitats span Alaska and the Northwest Territories, British Columbia to Oregon, the Great Plains and the Great Lakes, and areas near Texas and Florida.Full Answer >
The eggs of the tomato hornworm are deposited in late spring by adult moths on the underside of leaves. Within five days, hatching beings, and the larva passes through about six stages of development before reaching full growth within four weeks. These larvae burrow into the soil to enter the pupal stage. Adults develop in two to four weeks, and then they make their way to the soil surface.Full Answer >
According to the Lepidopterists' Society, the average lifespan of an adult moth varies by species. For instance, sphinx moths typically live two to three months, silkworm moths survive only about one week after emerging from their cocoons and yucca moths die within two days.Full Answer >
