Do Dragonflies Consume Caterpillars From Tents?

Dragonflies are carnivores that eat various insects, including flies, midges, and mosquitoes. They can also eat butterflies, moths, beetles, bees, and other dragonflies. Adult dragonflies are strong-flying insects with wings that hold horizontally when at rest and in flight. They eat other insects such as flies, midges, and mosquitoes, as well as smaller dragonflies. Prey is usually caught in mid-air, with the dragonfly using its long legs to catch its prey.

Adult dragonflies eat forest tent caterpillars, which are attacked by flesh flies that lay eggs on their eggs or bodies. The larva hatches and will eat any insect they can catch, including other dragonflies. Midges and mosquitoes make up the bulk of their diet, but fragonflies and Baltimore Orioles are known to dine on tent caterpillars. When ingested, B. t. kills tent caterpillars, preventing further damage to trees.

Caterpillars spin, shed, and eat at night, spinning web-trails so they don’t bite. Their larvae, however, eat forest tent caterpillars when they are inside their cocoons. No definitive research has been conducted on the toxicity of tent caterpillars, with some stating they are harmless while others suggest they are potentially toxic.

Eastern tents typically eat peach tree leaves, but no information is available on their diet. The fall webworm, Hyphantria cunea, appears in late summer and is a pale yellow caterpillar with black markings. It creates tents and feeds on insects.

What Is The Best Treatment For Tent Caterpillars?

Bacillus thuringiensis (Bt) is an effective, selective insecticide that targets tent caterpillars while being safe for other wildlife. Application involves spraying directly on foliage and nests, especially since these caterpillars primarily feed on deciduous and ornamental trees, including aspen, maple, ash, birch, oak, and wild cherry. Reducing their populations is essential, as large infestations can cause significant damage.

Identifying tent caterpillars is crucial; there are three main species in the US, each with unique preferences. For small infestations, manually removing nests and disposing of them in soapy water is effective. However, larger populations may require contact insecticides.

How Long Do Tent Caterpillars Stay Around?

FTC (Forest Tent Caterpillar) and ETC (Eastern Tent Caterpillar) are integral components of forest ecosystems, characterized by periodic population fluctuations. Typically, high populations emerge every 10 years, lasting 2-3 years, with notable clusters forming in spring under warm, sunny conditions. These aggregates can be significantly warmer than the surrounding air, especially on cool mornings. Their life cycle begins with eggs, laid in masses on twigs, hatching in early March, coinciding with leaf budding.

Initially, larvae are social, staying within their silk tents while they feed; however, as they grow and require more food, they disperse. After reaching maturity in 4-6 weeks, they may drop to the ground in search of additional foliage. These caterpillars only live for one year, with adults emerging after a pupation period of about three weeks and typically living for 5-10 days. The feeding phase lasts for a few weeks, with outbreaks generally defoliating a limited number of branches.

Despite their periodic surge in populations, outbreaks don’t follow a strict timeline and are influenced by various ecological factors. Although they can lead to visible defoliation, they rarely cause significant harm to trees. Thus, while FTC and ETC populations may rise and fall, they remain a consistent presence in forest habitats, adapting to seasonal conditions throughout their life cycle.
