What do Eastern eyed click beetles do?

Answered by Jarrod Smith

Eastern eyed click beetles, also known as eyed elaters, are fascinating creatures that play an important role in the ecosystem of deciduous forests. These beetles can be found commonly in the eastern part of our country, where they thrive in their natural habitat.

One of the key aspects of the Eastern eyed click beetle’s life is its choice of residence. These beetles prefer to live in deciduous forests, where there is an abundance of decaying logs. The larvae of these beetles can be found within these logs, where they undergo their growth and development stages. It is interesting to note that the larvae of the Eastern eyed click beetle feed on the grubs of longhorn beetles, another type of beetle commonly found in these forests. This makes the Eastern eyed click beetle a natural predator, helping to control the population of longhorn beetles.

When fully grown, the adults of the Eastern eyed click beetle can reach a length of 1¾ inches. This makes them quite large compared to other beetles. However, their size is not the only remarkable feature. The most striking characteristic of the Eastern eyed click beetle is the presence of eyespots on its pronotum, which is the area just behind its head. These eyespots resemble large eyes and serve as a defensive mechanism against potential predators.

The purpose of these eyespots is to create a visual illusion that can startle or confuse predators. When threatened or attacked, the Eastern eyed click beetle has a unique ability to flip itself into the air with a clicking sound. This action startles predators and gives the illusion that the beetle is much larger and more formidable than it actually is. The eyespots on the pronotum add to this illusion by mimicking the appearance of a larger animal with eyes. This defensive strategy often causes predators to hesitate or retreat, giving the Eastern eyed click beetle a chance to escape.

Eastern eyed click beetles are fascinating creatures that have adapted to their environment in deciduous forests. They contribute to the ecosystem by preying on the grubs of longhorn beetles, helping to control their population. The distinctive eyespots on the pronotum of the Eastern eyed click beetle serve as a defensive mechanism, creating an illusion that deters potential predators. These beetles are an excellent example of nature’s ingenuity and the intricate relationships within an ecosystem.
