Some of the tropical South American species are giants of the insect world, reaching lengths of 4. However, much of their length consists of the enormously long horns which project from the thorax and head.

The larvae increase in scarabaeirae greatly as they progress. The dynastine group is comprised of the “Rhinoceros beetles”, and the cetoniine group contains those species often referred to as the “Flower beetles”. The family Scarabaeidae is a large and diverse group of beetles with many representatives worldwide.
Cetoniines are usually characterized by brilliant coloration. 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.
Like the dynastines, the larvae of cetoniines are usually found within decomposing trees and other accumulations of old plant scaraabeidae such as composting piles of fallen leaves. Among the largest species are those in the genera DynastesMegasomaChalcosoma and Goliathus. Links to other web sites about beetles.
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. To enter the selection page, click on the Dynastes hercules image to the right. 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 of the heaviest insects in the world, the Goliath beetles of tropical Africa, are members of the cetoniine subfamily. Some species are highly iridescent, or are covered with a smooth, velvet-like texture patterned with stripes or spots.

On this site, I present profiles giving basic natural history information about a selected variety of scarab scarabaeifae species. Dynastines are best known for their immense size and the amazing horn-like structures that the males of many species possess.
A few specialized ones live within the nests of ants, where they feed on bits of organic sfarabaeidae within the detritus piles which the ants accumulate. 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.
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 familix beetle group.
The larvae of dynastines primarily feed on the soft, decaying wood of dead trees. World of the Wolf.
Their colors vary from dull brown to metallic gold. They range in size from diminutive to truly massive. Weights of nearly grams larval stage have been recorded for Goliathus.
