Davey, P., 2009: A species limited to the calcareous soils of south-east and central southern England, the larva feeding for at least two years within the stems or branches (up to 25mm in diameter) of the wayfaring tree (Viburnum lantana), and, less frequently of guelder rose (Viburnum opulus). In its final year of growth, the larva cuts a disc-shaped cap in the bark over the emergence hole; this structure is the only external evidence of the larva within. The moth emerges through June and July. In Dorset, many inland calcareous localities have been found to harbour the moth, especially where old scrub containing mature wayfaring tree remains untouched on chalk downland. This species tends to colonise single plants, leaving others nearby unaffected. Retention of good quantities of wayfaring tree as part of the downland scrub mosaic would assist with the conservation of this species in the county. Unfortunately such mosaics are seldom valued by conservation agencies, and continue to be reduced in extent or obliterated as they were during the reversion of downland to arable in the post-war years by farmers.
