On this site, I present profiles giving basic natural history information about a selected variety of scarab beetle species.
Among the largest species are those in the genera DynastesMegasomaChalcosoma and Goliathus. They range in size from diminutive to truly massive.

Links to other web sites about beetles. Some of the heaviest insects in the world, the Goliath beetles of tropical Africa, are members of the cetoniine subfamily.
They often require months to complete their growth, undergo metamorphosis within a protective cell, and then re-enter the outside world as adult beetles. Some species are scarabaeidaw iridescent, or are covered with a smooth, velvet-like texture patterned with stripes or spots.
The dynastine group is comprised of the “Rhinoceros beetles”, and the cetoniine group contains those species often referred to as the “Flower beetles”.
Information on the individual species pages will include distribution, measurements, biology, and when possible, photographs of both the adult and larval stages of each species.

Dynastines are best known for their immense size and the amazing horn-like structures that the males of many species possess. These structures are used mainly for defending feeding sites and during strength contests with other males over mates during the breeding season. The types of scarab beetles depicted on these pages will primarily be members of the subfamilies dynastinae and cetoniinae.
Like the dynastines, the larvae of cetoniines are usually found within decomposing trees and other accumulations of old scarxbaeidae material such as composting piles of fallen leaves. Some of the tropical South American species are giants of the insect world, reaching lengths of 4.

Their colors vary from dull brown to metallic gold. Weights of nearly grams larval stage have been recorded for Goliathus. The family Scarabaeidae is a large and diverse group of beetles with many representatives worldwide.

The larvae increase in size greatly as they progress. Cetoniines are usually characterized by brilliant coloration.

However, much of their length consists of the enormously long horns which project from the thorax and head. The larvae of dynastines primarily feed on the soft, decaying wood of dead trees.
There are many thousands of species in the family Scarabaeidae, and this site give you a glimpse of their diversity by presenting profiles of some of the better-known members of this beetle group. Although the vast majority of these “Rhinoceros beetles” are found within the planet’s equatorial rain forests, there are a few species that live in more temperate latitudes such as North America and Europe.
