![]() The length of time for the pupa to mature inside the cocoon depends on climate and temperature. A Hemaris thysbe caterpillar will molt (shed its skin) several times as it grows over the course of about four weeks.Īt maturity, the caterpillar climbs down to the ground and spins a silk cocoon in the dirt and leaf litter. In approximately a week’s time, a new baby caterpillar munches its way out of the egg casing. Eggs are commonly laid on the underside of leaves to help provide protection from birds and wasps. To accomplish this, she emits pheromones and, after mating, lays her eggs on the leaves of the host tree/shrub. It is the female hummingbird moth who must work to attract the attention of the gents. While the majority of moth species fly at night, Hemaris thysbe is a visible daytime flier. However, they are most common in the eastern half of the US. They may be found throughout the continental US and Western Canada. Hummingbird moths are strong fliers who are capable of covering large distances. Therefore, it is best to buy habitat plants from the smaller, (and local) true native plant nurseries. to be recognized or digested by our own US native bugs. There are many cultivars and European versions heavily marketed by large commercial nurseries as “good for pollinators.” Unfortunately, these plant versions may actually not have the correct pollen, nectar, sap, fragrance, etc. If planting a tree/shrub specifically to attract these little hummers, be careful to purchase a true US native plant. Favorite flowers include bee balm, verbena, and phlox as well as the flowers on their host fruit trees.Ĭaterpillars feed on the leaves of host trees/shrubs such as cherry, plum, hawthorn, honeysuckle, and viburnum.

This overlapping use of nicknames can lead to some confusion within casual literature regarding this moth family. These nicknames include hummingbird moth, hawkmoth, bee moth, sphinx moth, clearwing, and hornworm. There are over 1,400 individual moth species in this family, and they share a confusing mix of nicknames that are often used interchangeably. Hermaris thysbe moths are in the Sphingidae family. Otherwise, you may inadvertently toss the next generation of hummingbird moths in the trash. viburnum, cherry, plum) for these little guys, it is important to leave the leaf litter intact. Therefore, if you are lucky enough to have an appropriate host plant (e.g. Hummingbird moths build their cocoons on the ground within the leaf litter at the base of their host trees and shrubs. (However, actual hummingbirds beat their wings 50 – 60 times per second.) The figure eight pattern made by the wings allows both hummingbirds and hummingbird moths to hover in mid-air and to fly briefly backwards. The hummingbird moth beats its wings 30 – 40 times per second in a figure eight pattern that is similar to the pattern a of a real hummingbird. Native Plants for Birds, Bees, and ButterfliesįUN FACT: Tiny hummingbird moths strongly resemble real hummingbirds.
