Hawthorn shield bug

Hawthorn shield bug

Acanthosoma haemorrhoidale

A species of Acanthosoma

The hawthorn shield bug (Acanthosoma haemorrhoidale) is a common European shield bug. Its chief food is haws, the fruit of the hawthorn tree, but adults can overwinter on a diet of leaves, and individuals can be found on many potential food plants, including pedunculate oak, sessile oak and whitebeam. They may grow up to 17 mm (0.67 in) long, and are camouflaged in shades of green and brown. Like many so-called "stink bugs", they may release unpleasant odours when disturbed.

Distribution Area of Hawthorn shield bug
The hawthorn shield bug is found across Europe, from Portugal to Russia, and is common in the southern part of Great Britain. Its distribution appears to be spreading north, being reported as far north as Manchester only in 1892, but having now extended its range to Northern England and even the Scottish Highlands. In Britain and North Western Europe the species is generally active between the months of April and October, although specimens can reappear from hibernation during periods of unseasonable warm weather in the winter. The hawthorn shield bug is a distinctive species, but could be confused with the birch shield bug, Elasmostethus interstinctus.

Life Cycle of Hawthorn shield bug
Egg The eggs of hawthorn shield bug are often laid in clusters. They are tiny, and depending on the species may have varying colors. The embryonic development inside leads to the emergence of nymphs.
Nymph The nymph of hawthorn shield bug resembles a miniature adult without fully developed wings. These stages, with each molt, exhibit gradual development in size, wing buds, and coloration until they reach maturity.
Adult The adult hawthorn shield bug is characterized by fully developed wings, which are typically half-leathery at the base. Adults display a more vibrant coloration, are larger in size, and their primary focus is on reproduction and feeding.

Habitat Preferences of Hawthorn shield bug Through Different Life Stages
The eggs of hawthorn shield bug are typically found on the underside of leaves of the host plants, often in sheltered locations such as hedgerows or woodlands. Nymphs, persisting on the same plants, tend to be on the stems or leaves, seeking out areas rich in sap which is their primary food source. Searching for nymphs would involve inspecting these parts of plants during the warmer months. Adults of hawthorn shield bug are found in similar habitats as the nymphs but may also be observed on the flowers and leaves of a wider variety of plants, especially during mating season. To locate adults, one might look at sunlit leaves and flowers during late spring and summer.

Agricultural Pests

The adult and nymph stages of hawthorn shield bug feed by piercing and sucking the sap from leaves and fruits, compromising plant vigor. In high populations, this insect causes significant damage, leading to wilted, discolored foliage and deformed fruits, which may impact crop yields and quality, affecting local agriculture and economies.

Rectangle
Hurt Plant

Hawthorn shield bug inflicts damage on plants at both adult and nymph stages by feeding, primarily through sucking plant fluids. This leads to reduced vigor, wilting, and potentially severe yield losses if the infestation is high. It affects all types of plants, targeting leaves and fruits.
