Beetles are one of the most diverse groups of insects, with over 350,000 known species in more than 130 families. Among these, black beetles are one of the most common types of beetles. In fact, in their phylogenetic order, Coleoptera, there are more types of these creatures than any other.
Black beetles can be found in virtually all habitable terrestrial and freshwater environments. Knowing about different types of black beetles along with their location in the world can help people identify some of the more common genera of beetles.
In this article, we will uncover 10 different types of black beetles and find out how big they get and what makes them unique.
10 Types Of Black Beetles
The Cedar Beetle, also known as the Cicada Parasite Beetle, is a species of beetle in the family Rhipiceridae. These beetles are generally reported as flying around or crawling on trees. They have a parasitic relationship with cicada larvae, and female beetles lay their eggs on trees.
Cedar beetles are small, reddish-brown to black beetles that are approximately 1/8 inch (3 mm) long. Larvae are small, cream-colored, legless grubs.
These tiny beetles are relatives of the better-known mountain pine beetle and are found in the western United States. Cedar bark beetles are pests native to Texas and attack cypress and juniper trees.
Pine Sawyer Beetle
The Pine Sawyer Beetle, also known as the Whitespotted Pine Sawyer, is a species of beetle in the family Cerambycidae. These beetles are commonly known as sawyers or pine sawyers because the larvae bore into the wood of pine trees.
The Whitespotted Pine Sawyer is a native beetle that attacks diseased and damaged pine trees. Its range extends from Newfoundland to Florida, west to the Dakotas and Texas.
The Pine Sawyer Beetle is a slow, ungainly flyer and has very long antennae, often longer than their body, with the male’s antennae being longer than the female’s. These beetles are black or dark brown and can grow up to 1.5 inches (3.8 cm) long.
The Whitespotted Sawyer beetle is primarily a minor pest of coniferous trees, especially white pine, balsam fir, and species of spruce.
Rhinoceros beetles are a subfamily of the scarab beetle family, with over 1500 species and 225 genera known. They are commonly known as Hercules beetles, unicorn beetles, or horn beetles.
These beetles are named for the horn-like projections on and around the males’ heads, which they use to fight off other males and win the right to mate with females.
Rhinoceros beetles are herbivorous insects, and the adults feed on fruit, nectar, and sap, while the larvae eat decaying plant matter. These beetles can grow up to six inches (15 centimeters), making them some of the largest beetles in the world.
Rhinoceros beetles are found on every continent except Antarctica, and they live in woodland, parkland, hedgerows, and other habitats.
