What We Have Known about the Hawthorn Shield Bug’s Biology

Hanel L., Hanelová J.

The Hawthorn Shield Bug (Acanthosoma haemorrhoidale) is the largest phytophagous dendrophilous species of the family Acanthosomatidae in the Czech Republic. According to authors’ observations and literary sources, the eggs are laid only on leaves of the Rowan Tree, Hawthorn or Blackthorn. Parental (maternal) care does not exist in the species. In the article, the developmental stages of the Hawthorn Shield Bug and parasitic wasps of the genus Trissolcus sometimes invading their eggs, are documented by photos for the first time.
