Elasmucha grisea

Parent bug

Description

Elasmucha grisea, commonly known as the parent bug, belongs to the family Acanthosomatidae and is widely distributed across Europe and parts of Asia. This shield bug primarily inhabits deciduous trees, with a preference for birch (Betula), alder (Alnus), and hazel (Corylus). Adults and nymphs feed by sucking sap from leaves and young shoots, though their feeding activity generally causes little harm to the host plants. This species is widespread in Europe and is often soon on leaves or branches of the trees un Summer. Unlike many insects, Elasmucha grisea exhibits parental care, with females guarding their eggs and nymphs until they are mature enough to fend for themselves. In most cases, the impact of Elasmucha grisea is minimal, and it is not regarded as a serious threat to tree health. Its presence on trees is more of a natural part of the ecosystem, and large infestations are uncommon. Therefore, it is generally not considered a pest that requires control measures.

Symptom

Leaves and shoots may show mild sap-sucking damage, but this is rarely severe. No significant external symptoms are typically visible on infested trees. Adults and nymphs can be present.
