Ardis pallipes (Serville, 1823)

Ardis pallipes

One of the two Ardis species characterised by large punctures around the outer eye margins. Mostly black with the hind edges of the pronotum and tegulae white, as are the bases of the tarsal segments and tibia.

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.
