Larvae stay together and move by following a silk trail deposited by the foraging and feeding file's leader. Thus, it is an adaptive advantage to bask in groups. This hanging behavior does not appear at low population densities, presumably because it is more energetically costly and more conspicuous, since it can attract more males that can potentially interfere in the copulation process. The most common and damaging tent caterpillar found in urban areas is the forest tent caterpillar, M. disstria (Figure 3). Required fields are marked *. They approach trees and move around them, zigzagging and crawling on branches. Oregon Department of Forestry, 2007.

Dozens of caterpillars may congregate on these mats between feedings. [19] Ontogenetic changes in caterpillars reduce the risk of predation and as a consequence, predation-related benefits of group foraging decrease with time. Family - Tent Caterpillar Moths - Lasiocampidae . As the larvae mature, they disperse and become solitary feeders. Eggs hatch the following spring. Where spatially separated populations are phase-synchronized, the synchronization is thought to be due to the process of entrainment, that is, the synchronization of a circadian clock with the external environment. [17], Individual risk is lower in larger groups due to collective defense from predators, the dilution effect, and the selfish herd theory. Unlike related tent caterpillar species, the larvae of forest tent caterpillars do not make tents, but rather, weave a silky sheet where they lie together during molting.

However, when recurring defoliation accompanies other factors that can weaken a tree's health – drought, growth in poor soils and late growing season complete defoliation – the result of the infestation may kill the tree. Isolated caterpillars have been observed to fall off their host trees and perish. Under most circumstances, little lasting damage is caused to the trees; however, the disappearance of foliage is considered to be an unattractive nuisance.

The eastern tent caterpillar has a diagnostic solid white stripe down the back, while the forest tent caterpillar has a series of keyhole-shaped spots. It has also been reported that females emit a calling pheromone before they emerge from the pupae, causing an increase in male activity around the cocoon before they eclose. Instead, gypsy moth caterpillars have . Investigations suggest that red maples, sycamores and most species of coniferous trees are not fed upon.

Lappet Moth Phyllodesma americana The forest tent caterpillar, which is closely related to and resembles the eastern tent caterpillar, is characterized by fine hairs, blue markings on its side and back and white "keyhole . Grouping decreases growth rate via a decrease in food intake so ontogenetic changes toward more mobility and independence can be viewed as simple "scaling" relationships between caterpillars and food sources evolved to increase the benefits of individual foraging in later stages. Each abdominal segment bears a white spot, which . The forest tent caterpillar larvae also have a white hairy body, with the matured ones growing to 5 – 6.5 cm long. This behavior increases the percentage of eggs they fertilize as they delay their mated female from remating and reduce number of potential mates the female can have. Instead, the larvae are known to make silken sheets where they stay together during the molting phase. Twenty-six species have been described, six of which occur in North America and the rest in Eurasia. [10] However, this organized behavior and the high fidelity of caterpillars to pheromone hormone trails imply conservative foraging, which may trap caterpillars to poor food sources even if a better one is close by. The silk is produced by glands in the head and the tent provides protection from many natural enemies. 844-514-3980. The first matching photo we found was on the Wanderin Weeta blog, but alas, the moth is not identified. [13], Females begin ovipositing the day after copulation and do so in one batch during a single oviposition event. [13] There is a significant positive correlation between the body sizes of copulating pairs, which indicates that mating is not random with respect to size, presumably because of male-male competition for larger females. In addition, males have been seen approaching and moving around brown objects, suggesting that males also use visual cues to find females. [18] Caterpillar grouping behaviors change depending on food source; on less favorable food sources, caterpillar groups tend to splinter, thereby potentially increasing the risk for predation.
