Scarab Beetles: Basic Information and Removal

Green scarab beetle

Scarab beetles or Scarabs belong to Scarabaeidae family which houses over 30,000 species of beetles around the globe. However, the classification is not stable based on different competing theories because new theories are presented now and then. Many of the species of common scarab bugs mentioned in this article might not be recognized by this family as the species get the lower rank of subfamily or they might be elevated to family rank. For instance, some of the families have been removed including Bolboceratidae, Ochodaeidae, Glaphyridae, Geotrupidae, Pleocomidae and Glaresidae. Some of the well-known beetles currently defined consist of Hercules beetles, June beetles, dung beetles, rose chafers, Goliath beetles, and enormous rhinoceros beetles.

1. Appearance & SizeScarab Beetle resting on leaf

Scarab beetles are oval shaped, and stout-bodied beetles and have bright metallic colors. These beetles vary in length from 1.5 millimeters to 160 millimeters and can weigh up to 100 grams. Scarabs are characterized by their distinct-clubbed antennae which are made up of plates which are known as lamellae. These lamellae can be fanned out or compressed to sense different odors. Most of these beetles are monotone and are found in brown or black colors. The tropical Scarabs bear bright colors and different patterns. Some of the species have unnatural sheen just as that of a metal and some species are iridescent as well.

2. Food & Diet

Scarab beetles are omnivorous bugs, and the diet patterns vary from one species to another. Most of the Scarab beetles like to scavenge and recycle carrion, dung or decaying materials of plants. On the other hand, the Japanese beetles devastate the crops and are pure agricultural pests. Some of these beetles also eat fruits, insects, and fungi. There are some varieties of these beetles that live on slime left by the snails. Dung beetles consume the dung of all grazing animals. The dung beetle makes dung balls and carries them to large distances using their hind legs. These perfectly spherical dung balls are then buried in a place and females lay their eggs on it. The grubs grow in these balls to become a young Scarab beetle by feeding on the waste.

3. Reproduction

These beetles reproduce sexually and usually; there is not much courtship. The whole process begins when a female joins a male while creating a nest. Within a nest, both beetles create many underground chambers, however; the female does most of the construction. The purpose of the male is to get all the provisions for his female. The eggs are almost one-third the size of the beetle in length. Like all other beetles, Scarabs larvae also go through a complete scarab metamorphosis to become adult beetles. The C-shaped larvae of Scarab beetles are known as grubs and are of white or pale yellow color, and they feed on the food that is available in the nest. Most of the adult Scarabs are nocturnal, though many leaf chafers and flower chafers are also found active in the day time. The grubs spend most of their time under the debris or underground so that they are not exposed to the sunlight. Scarab populations have been very stable around the globe because they are found in different habitats and can consume decaying organic matter.
