Long-horned beetle

Ergates faber

A species of Ergates

The long-horned beetle (Ergates faber) is commonly found among the trunks of dead pine trees. They are known to be brown or dark red and have antennae that are as long as their body, thus explaining the name. They are a subject of preservation of the species in Poland due to the reducing forests.

Life Cycle of Long-horned beetle

Egg The egg is the initial stage where the embryo develops. Typically oval, long-horned beetle's eggs are often laid in protected environments and exhibit colors that camouflage with the substrate to avoid predators.

Larva As larvae, long-horned beetle's shape is elongated with a distinct head and segmented body. They lack true legs, bearing instead small prolegs. These grubs voraciously consume plant material, growing rapidly through several instars.

Pupal Transition occurs in the pupal stage, where long-horned beetle undergoes reorganization. Encased within a protective pupal chamber, they exhibit no feeding activity. The body is immobile but undergoes significant internal transformation.

Adult Emerging from the pupa, the adult long-horned beetle displays hardened exoskeleton, functional wings, and reproductive organs. Size increases and colors may brighten. This long-horned beetle is now capable of dispersion and focuses on reproducing.

Adult Size of Long-horned beetle

Interesting Facts About Long-horned beetle

Adult long-horned beetles have an unusual method of communication known as stridulation, producing sounds by rubbing together body parts, typically heard during the night.

How Can You Attract Long-horned beetle

Because long-horned beetle are wood-boring beetles, traps with bait made of fermenting natural materials such as tree sap or fruit might attract them effectively.

Habitat Preferences of Long-horned beetle Through Different Life Stages

The larvae of long-horned beetle are typically found in weakened or dead coniferous trees, where they bore into the wood, creating extensive tunnel systems as they feed on the internal tissues. Pupation occurs within the wooden galleries they excavate. Adults, after emerging from the pupal chambers, are often found on or near the same host trees, particularly during mating season when they seek out mates and suitable oviposition sites. To look for long-horned beetle, check the trunks and stumps of conifers in forests for signs of larval boring, such as sawdust or exit holes, while adults may be seen on the bark surface or flying in the vicinity during warm months.

When is the Best Time to Observe Long-horned beetle

Long-horned beetle are most active and easier to find during warm months, especially in spring and early summer when adults emerge to mate.

What is the Best Weather to Observe Long-horned beetle

A warm and humid climate is generally more suitable for finding long-horned beetle, as such weather conditions promote active movement and reproduction.

How and Where Can You Find Long-horned beetle at Different Life Stages

Larva Long-horned beetle larvae are wood borers and can be found within dead or dying trees. Search for them by examining trees with signs of damage or by peeling back the bark to reveal burrows and larvae tunnels.

Pupal During the pupal stage, long-horned beetle pupae develop inside the wood. To find them, look for emerging adults near the surface of infested wood, or carefully split logs to find the pupae chambers.

Adult Adult long-horned beetle can be observed on or near host trees. Spot them by looking for large beetles on tree trunks or inspecting around lights at night, as they might be attracted to artificial lighting.
