). The larvae were attached to the underside of a leaf and they were generally aggregated in that one or a few individuals occurred per leaf. Younger larvae skeletonised the leaves and made holes in the leaf, whereas larvae of later instars attacked the leaf up to its edge. Larvae fed on both younger and older leaves. One large patch of flowering plants clearly harboured fewer larvae than the smaller and more numerous spots of non-flowering plants. The larvae being kept in rearing still appeared as healthy, despite the fact that the offered leaves (during November 2014) were less fresh and rather decaying. A couple of plant species and varieties were also offered to them to roughly establish their diet breadth.

The bioassay consisted of placing seven ant workers and one larva settled on a host plant leaf in an open box, the interactions being then filmed. As far as no ant contacted the larva, the latter remained merely immobile. But once contacted, the larva instantly raised its abdomen and directed the apical filaments towards the aggressor (Fig.
