Widely distributed in the whole world, the scarab beetles number more than 20000 species, some of great size (Rhino beetles, Goliath beetles, ...).
Of various shapes, generally graceful, often adorned with bright or metallic colors, the scarab beetles are one of the most numerous and homogeneous families.
Scarab beetles larvae are phytophagous or saprophagous. The phytophagous ones develop generally in the ground at a little depth, living on plant roots ; they are thereby very harmful for crops (for instance the Chafers). The saprophagous or saproxylophagous species live in mould or manure heaps, mould of old tree hollows, more or less rotted wood (for instance the Flower beetles). And last, many species are coprophagous and can be found in dung and in excrement (for instance the Dung beetles).
These insects, except the coprophagous ones whose adults live in the excrements as well as their larvae, can be found at adult stage on flowers, low plants, shrubs, tree foliage. They are often pests, whether because they eat flowers stamens (Flower beetles), or stripping young trees of their leaves (Chafers), or also devouring shrub buds or young sprouts.
By reason of the diversity of the scarab beetles, we have detailed several families in the menu on the left.
