Male Vs. Female. Asian Longhorned Beetle


If you aren’t an insect expert, or even a fan of bugs in the slightest, chances are you find it difficult to tell one leggy bug from a similar one. However, determining which kind of insect is popping up in your garden, atop your trees, and even inside your home is crucial – if you aren’t certain which bug is which, you may not be able to stop their destruction or invasion, leaving you with a long-lasting problem. Of course, in addition to figuring out which bugs surround your home and your property, it’s also important to know if males or females are a bigger issue. Here’s how to tell the Asian Longhorned beetle, a common pest, from others, and its female insects from its male.

It can be somewhat simple to spot an Asian Longhorned beetle – you just need to take a look at its spots. Typically, the Asian Longhorned beetle is a large insect, its body stretching anywhere between 0.75 to 1.25 inches in length. It also features extended black and white antennae, and a body covered in white spots in an irregular pattern. Although they first originated in Asia and its many countries, the Longhorned beetle has become a prevalent species of beetle in the United States. If you’re having particular problems with the hardwood trees that line your yard, this beetle could be the source; it’s known to eat many different hardwood species, and remains alive all the way from late spring into late fall.

If you’re trying to tell the males from the females in the Asian Longhorned species of beetle, you’ll want to give their antennae a very close inspection. The male beetles feature antennae that are considerably longer than their bodies, while the females have antennae that end right about where the bulk of their bodies do. You may also want to inspect the areas in which you’ve spotted Asian Longhorned beetles on your trees and other plants – females provide a distinctive mark when they’ve laid eggs. In the summer, fall, and late fall days, the females lay eggs in the bark of trees. In order to keep their future offspring safe, the Asian Longhorned females will chew depressions of various sizes into the tree bark, and then lay exactly one egg in each spot.
