Ardis sulcata

Recorded locally in England and Wales north to Yorkshire (Musgrove, 2023).

One of the two Ardis species which are characterised by large punctures around the outer eye margins. Entirely black, but the knees and front of fore and middle tibia and tarsi brown.

Eggs are positioned near the mid-vein of folded terminal leaves on a growing tip of roses, especially rambling roses. Emerging larvae intially feed on the leaves before burrowing into the shoot. The presence of a larva is indicated by a small hole with frass deposits. The terminal leaves soon wilt and die. The eonymph exits the stem and pupates in the ground.
