(Chrysomelidae) This family includes slightly more than 35,000 species existing worldwide. Larvae and adults are mainly herbivorous, and some, depending on the species, are more or less connected to a group of plant families. The species of this family often exist in groups on tree leaves and weeds. Some species of this family, such as Bruchids, exist on seeds of fodder plants, inside which they complete their cycle and their larvae grow. Some species are very harmful to agricultural plants and stored foodstuff. Many of these species are toxic as they have developed a system of chemical defense.
