Eyed hawk-moth

The Eyed hawk-moth (Smerinthus ocellatus) is a species of moth belonging to the family Sphingidae. It is widely recognized by the prominent, eye-like markings on its hindwings, which are exposed only when the insect feels threatened, acting as a defensive mechanism against predators.

This insect is considered a pest in fruit orchards and gardens. The larvae (caterpillars) feed primarily on leaves of various fruit trees, including apple, pear, plum, and cherry. While they also inhabit willows and poplars, their presence in home orchards can lead to significant foliage loss on young, vulnerable trees.

The life cycle undergoes complete metamorphosis, including egg, larva, pupa, and adult stages. The insect spends the winter in the pupal stage, buried in the soil. Adults emerge in late spring or early summer to mate and lay eggs, typically on the underside of host leaves, ensuring a food source for the hatching larvae.

The primary damage is caused by the voracious appetite of the caterpillars. They consume the leaf tissue, often starting from the edges and moving inward, leaving only the midribs behind. Severe infestations can defoliate portions of the canopy, stressing the host tree and potentially hindering its development or future crop yield.

Effective management and protection strategies include:

• Tilling the soil beneath the canopy in autumn to expose and destroy overwintering pupae.
• Manual collection and removal of caterpillars in smaller garden settings.
• Encouraging natural predators such as insectivorous birds and parasitic wasps.
• Selective use of insecticides if infestation levels exceed economic thresholds during peak larval activity.
