Tent Caterpillars: Controlling and Prevention

Tent Caterpillars Prevention

Eastern tent caterpillars are common in the eastern regions in the United States of America. Otherwise known as tent worms, they are more of a nuisance than an actual threat. Because these worms have a tendency to multiply in quick time, it is imperative to control them as soon as possible to prevent their infestation. This is a major step in the direction of tent caterpillar control.

Most people tend to confuse tent worms with fall webworms. However, there are some differences between the two species of worms, both in terms of appearance and a number of other features. Known for being active towards the beginning of the spring season, tent worms prefer to build nests in the branches of trees. They either prefer ornamental fruit trees or wild cherry trees for the purpose. Also, they are adept at nesting in the forks of maple and willow trees

By and large, tent worms do not cause any major issue except for infestation. However, when left unchecked, they can multiply in large numbers, thereby giving one a hard time to bring the situation back to normal at the subsequent stages. By building colonies, tent caterpillars can have an adverse effect on trees, besetting them in several ways. For instance, trees that get affected by the multiplication of tent worms not only show a lack of growth but also become susceptible to a number of other diseases. More often than not, it generally happens with deciduous trees or shrubs.

Other than deciduous trees, such patterns are also common in neglected orchards or roadside trees. Apart from defoliation, the larvae of the worms are also known to produce tents or unsightly webs that can linger on the crotches of branches for several days. The webs offer an additional layer of protection to the worms from predators and a number of other elements that can affect their growth. This makes tent caterpillar control more complicated than what it appears to be on the surface.

The Living Habits of Tent Caterpillar

Tent caterpillars generally spend the winter or live through it in a collection of numerous eggs. These eggs normally hatch in the spring – the time when cherry leaves also start to unfold. The newly born caterpillars assemble at a crotch and construct a silk web in the branches of the cherry tree. While younger caterpillars feed during the daytime and live in the tent at night, the older ones do the opposite to survive.

Living Habits of Tent Caterpillar

Upon maturity, a larva measures up to 2 inches. In terms of appearance, it is black with a white stripe at the back and blue spots among yellow lines that run along its length. The body is characterized by the growth of fine hairs all along. Once matured, a caterpillar looks for a new tree, leaving the host tree, to spin a cocoon. It will generally choose a fence post, debris on the ground, sides of buildings and tree trunks for the purpose. Eventually, it develops into a moth within a couple of weeks’ time. Thereafter, it grows into an adult moth and mates. In the process, it lays eggs that overwinter and the cycle continues.

Moths look like large-sized butterflies with a distinctive appearance. They have reddish-brown wings with white stripes that run diagonally on two front wings. On average, only one generation of a moth grows each year after spending nine months in the egg stage.

In broad terms, the lifecycle of a caterpillar can be divided into the following stages:

  • Egg:Tent worms lay eggs in masses that generally range between 200 and 400. A brownish grey material protects the eggs from different weather elements. As for appearance, the egg is about 1/25 inch or 1mm in length.
  • Larva:About 2 inches long, the larva of a fully developed eastern tent caterpillar is about 2 inches long with fine and yellowish brown hairs. Apart from black and bluish spots, there is also a distinctive light stripe on its body down the middle.
  • Pupa:This is the stage wherein the caterpillars show signs of maturity. This also the juncture wherein a caterpillar shows the signs of transitioning into its adulthood.
  • Adult: Once they reach their adulthood, caterpillars look totally different in comparison to their appearances in the previous stages. They develop wings and become moths.
