#INCHWORM AND STARTRAIL MURDER SKIN#
Inchworms eat so much that they outgrow their skin and have to molt several times before they’ve eaten their fill. It is this feeding that can cause some conflict between inchworms and gardeners, but we’ll get to that in a minute. In spring, the eggs hatch and inchworms start feeding, usually at night. Inchworms start out as the eggs of Geometer moths, laid on the underside of leaves. If you would like more information about bacillus thuringiensis or to purchase products containing bacillus thuringiensis please visit. Bacillus thuringiensis, a wilt pathogen, is available to gardeners to help control infestations. Wilt disease causes the inchworms body to rot. Natural diseases and parasites also control inchworms.

Birds, yellow jackets and paper wasps also feast on inch worms, so allowing these types of animals and insects to roam free in your garden or around your crops should help control your inchworm population.
Inchworms have natural predators, specifically Trichogramma wasps. The larvae prefer vegetable gardens and they eat a variety of crops including: celery, cabbage, cauliflower, radishes, Brussels sprouts, beans, parsley, broccoli, potatoes, tomatoes, and peas. Once they’ve had their fill, the larvae spin cocoons similar to the ones used during the overwinter process. Once the larvae emerge, they feed for two to four weeks. The adult lays its eggs, typically on the surface of leaves. These creatures like to hang out in apples, elms, oaks, lindens, sweetgums, and a wide variety of other shade and fruit trees.Īnother type of inchworm, also called Looper and Cabbage Looper, overwinters as green to brown pupae tightly wrapped in cocoons (not webs) of white thread. Cankerworms feed on shrub foliage and tree foliage. Also called measuring worms, cankerworms vary in color, but their bodies consist of long horizontal stripes. It just so happens that one of the most destructive types of inchworms, called cankerworms, produces soft silk threads as they drop from trees to evade predators. In some cases, these thin lines are made of silk. Much like spiders, some inchworms have the ability produce thin delicate lines. They have the ability to stand erect and motionless when poked or prodded in any way. Inchworms travel by drawing their hind end forward while gripping the earth with its prolegs. Their colors run the gamut from brown and black to bright green.Īlso referred to as loopers, measuring worms, and spanworms, inchworms have three pairs of legs at the front end and two to three pairs of prolegs or larval abdominal appendages at the rear.
They have smooth, hairless bodies, and they typically grow up to one inch in length. Inchworms do, however, have many common characteristics. Some inchworms (also “inch worm”) are considered average while others are considered extraordinary. This large, widely diffused group has more than 1,200 species indigenous to North America. An inchworm is the larvae of moths of the family Geometridae (phylum Arthropoda, class Insecta, order Lepidoptera).
