Intolerance for Cold Weather: Asian Lady Beetles don't like cold weather and have been known to crawl into any cracks of a home they can find, eventually making their way inside looking for warmth.Most of the spots on the Asian Lady Beetle are dark and black, whereas others have lighter spots, with some having no spots at all. Color and Spots: They can come in a variety of colors, as you can see from the photographs in this article."M" or "W" Design: The Asian Lady Beetle looks a lot like the good ladybug, but the main difference is that they have an "M" or "W" design right behind their head in an area that is a whitish color.There are some ways to distinguish the "bad" from the "good" ladybugs.

Photography by Larry Jernigan How to Recognize an Asian Lady Beetle This photograph was taken by an old friend of ours, Larry Jernigan of Heber Springs, Arkansas. This is considered "the bad beetle," mostly because it likes to spend its winters indoors. What Don't Cicadas Eat?Ĭicadas do not prey on other insects, are very unlikely to bite someone, do not suck blood, do not transmit any known diseases to people or animals and do not possess the type of mouthparts that enable them to consume the plants in your vegetable or flower gardens.This is a photograph of an Asian ladybug. Cicada nymphs may not directly cause plant damage, but plant growth may be reduced if there is an extremely large number of nymphs feeding on the plant’s root system. The xylem is the part of the plant that functions to transport moisture and nutrients from the roots to the plant’s leaves. Nymphs use their piercing mouthparts to puncture the roots and suck up the fluids located in the plant’s xylem. Nymphs do not feed on plant leaves or stems instead they feed on plant roots and usually do not cause noticeable damage to the plant. Preferred hosts for cicadas include trees such as oaks, maples, willows and ash species, but cicadas are very opportunistic feeders that will likely be attracted to whatever large plant is nearby the nymphs underground habitat. AdultsĪs adults they feed on plant fluids from the young twigs of trees and woody shrubs.Ĭontrary to popular opinion, adult cicadas do not cause serious plant damage from their feeding activities, but do damage plants as the result of their behavior of cutting small slits in the plant they use for places to deposit their eggs. Cicadas go through three life cycle developmental stages – egg, nymph and adult. So, what do cicadas eat? The answer to this question depends upon the cicada’s development stage. Unlike locusts, cicadas usually do not heavily feed on plant leaves. CicadasĬicadas have piercing/sucking mouthparts (similar to a mosquito) they use to obtain their nourishment from below ground roots and young twigs. Locusts have chewing mouthparts that enable them to chew and consume almost all or any part of a plant that is above ground. While locusts look like grasshoppers and are ravenous consumers of plants, cicadas are much different in the amounts and parts of plants they feed upon. It is important to differentiate cicadas from locusts since they are two very different groups of insects.
