Arge berberidis

Berberis sawfly

Description

Berberis sawfly Arge berberidis is a pest that specifically targets plants from the Berberis genus, commonly known as barberries. The adult Arge berberidis is a slender, wasp-like insect characterized by its black body and transparent wings. The adult Berberis sawflies Arge berberidis can be observed flying around their host plants during the months of May or June. They have a preference for resting in shaded areas, where they mate and search for suitable locations to lay their eggs. Once hatched, the larvae feed on the foliage, and severe infestations can result in complete defoliation of the affected plants. The larvae can be found from May to October and measure approximately 15-18 mm in length. They have black heads and creamy white bodies adorned with numerous black and yellow markings. During late summer, when fully developed, the larvae drop to the ground and construct cocoons whre they overwinter. They hatch the next spring. Regular inspection and early detection of sawfly larvae are important for pest control.
