The adult cottonwood borer is a large longhorn beetle with a black-and-white coloration and black antennae as long or longer than the body. [5] The white portions are due to microscopic masses of hair. [6] The larvae have legless, cylindrical, creamy-white bodies with a brown-to-black head and grow up to 38 millimetres (1.5 in) long.
Alaus oculatus can reach a length of about 25–45 millimetres (1.0–1.8 in). [2] They have an elongated body, black in color throughout. The pronotum exhibits a large oval patch of darker scales, framed in white, on each side - the common name of the beetle derives from this feature.
The females range from a dark chestnut brown to silky white, but the males are normally brown/white/black or black/white. [1] Goliath beetles, while not currently evaluated on the IUCN Red List, are facing growing conservation challenges across their African range due to habitat loss, over-collection for the international pet trade, and the ...
Monochamus scutellatus, commonly known as the white-spotted sawyer or spruce sawyer or spruce bug or a hair-eater, [1] is a common wood-boring beetle found throughout North America. [2] It is a species native to North America.
Adults are very large insects with bodies ranging from 1.7 to 3.9 cm (0.67 to 1.54 in) in length and antennae which can be as long as 4 cm (1.6 in) or 1.5–2 times longer than the body of the insect. [2] They are shiny black with about 20 white spots on each wing cover and long antennae conspicuously banded black and white.
The more than 6,000 described species have a global distribution and are found in a variety of habitats. They are oval beetles with a domed back and flat underside. Many of the species have conspicuous aposematic (warning) colours and patterns, such as red with black spots, that warn potential predators that they taste bad.
These beetles can be difficult to identify because of their variations in color, spot size, and spot count of the elytra. The easiest way to identify H. axyridis f. succinea is to look at the pronotum and see whether the black markings look like a letter "W" or "M". This species has more white markings on the pronotum than have most native ...
Goliathus albosignatus is a species of beetle of the family Scarabaeidae, described by Carl Henrik Boheman in 1857. It is one of several species of Goliath beetles that inhabit Africa, but it is the only one exclusively found in subtropical sections of the continent.
