Pale eggar

Pale eggar

Trichiura crataegi

A species of Trichiura, Also known as Pale eggar moth

Adorned with a cloak of fine hairs, pale eggar flutters predominantly during twilight hours. Its coloration is subtly calibrated for camouflage, merging seamlessly with the autumnal foliage it frequents. The early life stages are marked by voracious leaf consumption, yet emerging into maturity, the diet transitions remarkably, as adults lack functional mouthparts, relying on reserves accumulated during their larval phase for sustenance.

When is the Best Time to Observe Pale eggar
The best time to find pale eggar varies by life stage; eggs are typically laid in the fall, caterpillars can be found from spring to late summer, pupae can be found in the late summer, and adults are usually active from late summer to early fall.
Rectangle
What is the Best Weather to Observe Pale eggar
Calm, warm, and dry nights are ideal for finding adult pale eggar, while caterpillars and eggs can be found in mild weather conditions during daylight hours.

How and Where Can You Find Pale eggar at Different Life Stages
Egg Egg clusters of pale eggar are usually laid on the underside of leaves of host plants. Search through host plant foliage, inspecting the undersides of leaves for small, rounded eggs.
Larva Pale eggar larvae can be found on or near their host plants which include hawthorn, blackthorn, and several other deciduous trees. Look for signs of feeding, such as notches in leaves or frass (caterpillar droppings) beneath host plants, to locate them during the day.
Pupal Pale eggar pupae are typically hidden near the ground in leaf litter or soil, or sometimes on the host plant. Gently brush away litter at the base of host plants or inspect the bark and crevices of the plant itself to find them.
Adult Adult pale eggar are often nocturnal and attracted to light. Use a light trap on a calm night or set up a white sheet with a light source behind it to attract and observe them. Alternatively, during the day, check the resting places such as tree trunks where they might be camouflaged.

Are Pale eggar harmful to humans?

Most of the larvae of the leaf moth family are poisonous bristles, which will release an irritating liquid when broken. If they are stabbed by these burrs, they will immediately produce tingling and burning sensations, and may also cause nausea and vomiting. In severe cases, the numbness and swelling that accompanies it may extend to the entire arm, leg, or other area.

Garden and Landscape Pest

Larvae of pale eggar are known to chew plant tissues, defoliating host plants like roses, fruit trees, and hedges. Initially, damage may appear mild but can escalate to severe with high infestations, leading to significant leaf and fruit loss, impacting plant health and potentially reducing fruit yields. Large populations might necessitate pest control to mitigate impacts on garden aesthetics and productivity.

Rectangle
Hurt Plant

As pale eggar larvae engage in feeding, they voraciously chew plant tissues, predominantly leaves. The host plants including hawthorn, blackthorn, and birch exhibit defoliation. Prolonged feeding can result in reduced photosynthesis, stunting the plant’s growth and weakening its overall vigor, often leading to compromised plant health.

Small eggar
Small eggar

Wrapped within a cocoon of silken threads, small eggar undergoes a remarkable transformation, emerging as a moth with a distinctive wing pattern. As a caterpillar, it consumes deciduous leaves, vital for surviving winters in a hibernacula. In contrast, the adult is known for its short-lived nocturnal activity, relying on fat reserves as it seeks mates, foregoing feeding altogether.

Eastern eggar
Eastern eggar

The larval stage of eastern eggar boasts a remarkable adaptation for overwintering – the creation of a tough, silk hibernaculum that shields against freezing temperatures. This early life cocoon is not found in all Lepidoptera. As adults, these creatures exhibit pronounced sexual dimorphism; males have feathery antennae used to detect pheromones, an attribute that females lack. The species is nocturnal, with activity patterns tightly linked to the lunar cycle, and predominantly feeds on the leaves of deciduous trees during its larval phase.
