May - July. England and Wales. Shiny green forewings, the Cistus is generally smaller than the Scarce Forester or the Forester. Often found near common rock-rose, it frequents open chalk and limestone grassland.
One of three similar species, this iridescent green moth can be difficult to distinguish from related species. However, it is generally smaller than either the Forester or Scarce Forester, and the presence of good quantities of the Cistus Forester’s foodplant, Common Rock-rose, can be a useful indication of this species.
Active by day, the moth visiting flowers such as Common Rock-rose, Kidney Vetch, Wild Thyme and Common Bird’s-foot Trefoil.
