DESCRIPTION:The Harlequin or Asian ladybird (Harmonia axyridis) is an inva
 sive species with a great number of colour morphs. One of these morphs (f.
  succinea) – the most common in invasive populations – also shows stri
 king phenotypic plasticity. When reared in a cold environment dark melanin
  pigmentation is increased\; a response that is in line with the thermal m
 elanism hypothesis. Using a large-scale selection experiment I am investig
 ating this plastic ability and the underlying heritable variation. Full-si
 bling groups are split over two temperatures\, photographed\, and analysed
  using image analysis software\, in order to quantify the degree of plasti
 city (Reaction Norm) for each family. Now\, nearing the end of the second 
 generation\, promising early results will be shown.
