Did You Know? 15 Incredible Emerald Ash Borer Facts

Read these interesting facts about emerald ash borer to learn more about this species of beetles that lives on millions of ash trees to complete their life cycle.

The emerald ash borer beetle is a species of invasive, non-native beetles first discovered in parts of Michigan near Detroit in early 2002. As of 2018, these invasive beetles have been found in over 35 states of North America and even some parts of Canada. These beetle are an alluring metallic green in color and are mostly found along with the natural resources of ash tree wood as they feed on the bark and wood of these ash trees. These beetles undergo complete metamorphosis wherein a female beetle lays about 60-90 eggs on the host tree's bark, which then develops into larvae, then pupa, and then adult beetles. These invasive pests are known to target and destroy ash trees and their wood. Therefore, the range and spread of this harmful pest are updated every month by forest services like the USDA forest service department and the USDA Animal and plant health inspection service department. These EABs are also spread as the local people move firewood to the neighboring areas, which is why the forest departments also aim to prevent the infestation of the other regions by avoiding the transport of firewood.

Here on our page, we have lots of interesting facts on the emerald ash borer that everyone will enjoy. If you like these, do also read our dragonfly facts and cabbage white butterfly facts too.

Emerald Ash Borer Interesting Facts

What type of animal is an emerald ash borer?

EABs are a species of invasive beetle native to North America. They live and feed on the wood and bark of ash trees which leads to the infestation of the tree and ultimately its destruction.

What class of animal does an emerald ash borer belong to?

They belong to the class of Insecta.

How many emerald ash borers are there in the world?

The exact number of emerald ash borers is yet not known.

Where does an emerald ash borer live?

Emerald ash borers are species of invasive beetles native to northeastern China, Japan, and North America. Emerald ash borers live on millions of ash trees to complete their life cycle.

What is an emerald ash borer's habitat?

An ash borer (Agrilus planipennis) is an invasive species of beetles that are usually found along with the natural resources of ash trees. They live on the bark and wood of ash trees and tree-shaped exit holes.

Who do emerald ash borers live with?

They are usually found to exist in a group of their own.

How long does an emerald ash borer live?

An emerald ash borer has a lifespan of about one to two years.

How do they reproduce?

Emerald ash borer beetles usually mate on the trunk of an ash tree, and each male and female EAB copulate with multiple partners to complete their reproduction process. Once a male finds a female to mate with, the male drops out of the air onto the female, and insemination occurs.

After copulating with a mate, females begin to get lay eggs for around four to six weeks. On average, they lay around 60 eggs which then hatch inside two weeks to produce adult beetles.

What is their conservation status?

The conservation status of EAB beetles is not yet evaluated.

Emerald Ash Borer Fun Facts

What do emerald ash borers look like?

Emerald ash borers or EAB are elongated, cylindrical-shaped, slender beetles. The emerald ash borer is bright emerald green in color. Adult emerald ash borers have a coppery-red abdomen that's hidden beneath their wings.

An emerald ash borer, also called EAB, is roughly a size of a penny.

How cute are they?

The EAB is not as cute in appearance as one would think. However, they are rather captivating to look at, being a shimmery emerald green that shines bright in the sun.

How do they communicate?

The emerald ash borer is known to communicate using visual and chemical cues. EAB beetles have a series of chemoreceptors accustomed to understanding their setting, victimization style, and smell.

How big is an emerald ash borer?

EAB beetles are 0.33 in (0.85 cm) in length. They are almost eight times smaller in size than elephant beetles that have a size range of 2.75–4.75 in (7-12 cm).

How fast can an emerald ash borer run?

The exact speed of EAB beetles is yet not known.

How much does an emerald ash borer weigh?

The EAB beetle weighs somewhere around 0.0017 oz (0.05 g).

What are their male and female names of the species?

There is no specific name given to the males and females of this species of EAB beetles.

What would you call a baby emerald ash borer?

A baby EAB beetle does not bear any special name, just like an adult EAB beetle.

What do they eat?

Emerald ash borers (EAB) are folivores within the adult section and lignivorous within the larval section. As adults, these EABs feed on the leaves of ash trees, destroying their vascular vessels, which ultimately leads to the death of these infested ash trees. They are an invasive species of insects and are therefore regularly checked on through the forest department before they become the cause of the deaths of a large number of infested ash trees.

Are they dangerous?

These EAB beetles pose no direct threat to humans; however, their spread has killed over tens of millions of infested dead ash trees within the US and Asia, which has ultimately lead to around 15,000 human deaths from cardiovascular disease and an extra 6,000 deaths from lower respiratory disease. These EABs are spread because they move firewood in the local area.

Would they make a good pet?

No, these bright metallic green beetles will not make good pets because they are the most destructive invasive insects to ash trees and are indirectly dangerous to humans as well.

Did you know...

Emerald ash borer (EAB) pests from North America are solely capable of naturally dispersing themselves and also by means of firewood transportation.

Some other fascinating beetles include the green scarab beetle, soldier beetle, fungus beetle, and jewel beetle.

A variety of peckerwood species are found within the emerald ash borer's native geographical local home in China, North America, which is famed to prey upon the emerald ash borer (EAB) larvae.

The emerald ash borer (EAB) is now recognized as a harmful pest in North America.

The range and spread of this harmful EAB beetle pest by firewood transportation are updated every month by the animal and plant health inspection service and forest department.

EAB feeds exclusively on ash trees but is found to feed on some non-ash trees in parts of North America.

If you see an EAB beetle, then you should either contact the forest department near you or apply some insecticide or pesticide on the tree's infested area yourself.

How long does it take for an emerald ash borer to kill a tree?

Little trees could die within one or two years of changing into overrun when EAB beetle populations are high, and huge trees die within three to four years of the same.

The EAB beetle larvae stage is chargeable for the infestation that results in the death of its host. The larvae of EAB feeds below the tree bark, eventually damaging the tree's ability to move water and following nutrients from the soil to the ash tree leaves, leading to tree decline and death.

Can a tree recover from emerald ash borers?

These North American emerald ash borer or EAB beetle species sometimes need a minimum of a couple of years to kill an otherwise healthy tree. Overrun trees, with extra care, can be saved. Even those with a good quantity of cover decline can recover completely from EAB infestation. However, if the native tree has already suffered a 50% decline, then recovery from an EAB infestation is less likely. Ash tree mortality from EAB beetles is often prevented by treating infested trees with pesticides. However, it's a semi-permanent commitment. It takes nearly two to four years for the signs of the EAB infestation to manifest on millions of ash trees. Therefore, the range and spread of the harmful beetle pest are updated every month by the USDA forest service department and the USDA Animal and plant health inspection service.
