Early Thorn

Early Thorn

Selenia dentaria

A species of Selenia

Perched on a branch, early Thorn displays a mastery of camouflage with its textured wings perfectly mimicking the rough patterns and colors of tree bark to elude predators. During its larval stage, this creature is exclusively herbivorous, feeding voraciously on a variety of deciduous trees, which it later abandons for a brief, non-feeding adult life, devoted entirely to reproduction.

Habitat Preferences of Early Thorn Through Different Life Stages
The eggs of early Thorn are typically laid on host trees or shrubs, often where the leaves can provide immediate food upon hatching. Caterpillars of early Thorn are found munching on leaves in wooded areas or gardens where host plants are plentiful. For pupation, they might choose a sheltered spot under loose bark or in leaf litter. Adults, having emerged from pupae, are usually spotted in similar habitats, such as forests or hedgerows, resting on tree trunks or foliage, particularly during the night as they are nocturnal. To observe these different stages, you would meticulously examine the foliage of host plants for eggs or caterpillars, sift through leaf litter or probe under bark for pupae, and venture out at night with a light source to attract and spot the winged adults.
Rectangle
When is the Best Time to Observe Early Thorn
The best time to find early Thorn is during their active flying period for adults, which usually spans from spring to late summer, though specific months may vary by location. Caterpillars can be sought after when host plants are in full leaf, typically in late spring to midsummer.
Rectangle
What is the Best Weather to Observe Early Thorn
Finding early Thorn is most successful in dry and warm conditions, as wet or cold weather can cause them to be less active or seek shelter. The adults are often easier to spot on calm nights when they are attracted to light sources.
Rectangle
How and Where Can You Find Early Thorn at Different Life Stages
Egg Early Thorn eggs are usually laid on the leaves of host plants. Look for tiny, round or oval-shaped eggs on the undersides of leaves, particularly where the caterpillars feed.
Larva Early Thorn caterpillars are relatively camouflaged but may be found by inspecting the host plants they feed on. Look for notched or chewed leaves as an indicator of their presence.
Pupal Early Thorn pupae can sometimes be found attached to leaves or twigs, or within a loose cocoon in the leaf litter. Search near the base of host plants or in nearby detritus for these hidden pupae.
Adult Early Thorn adults are moths that can be found resting on the bark of trees or on the leaves of host plants during the day. At night, use a light source to attract them, as many moth species are nocturnal and drawn to light.

Hurt Plant

Larvae of early Thorn feed on plant leaves indiscriminately, leading to defoliation that can range from mild to severe, based on pest numbers. Defoliation stunts growth and reduces plant vigor.
