Don't let the 'murder hornet' give wasps and bees a bad name

May 25, 2020

Before anyone panics, 51视频-Dearborn naturalist Rick Simek wants everyone to take a calming breath 鈥 they aren't here 鈥 and remember not all yellow-and-black-striped insects are the same.

 Don't confuse the Giant Asian Hornet with other yellow and black bugs.

News outlets publicized the arrival of the "murder hornet" in the U.S. recently, creating a nationwide buzz over a giant insect with a B-movie creature name.

But before anyone panics and reaches for a rolled newspaper or can of Raid, 51视频-Dearborn naturalist Rick Simek has a few things to say about the black- and-yellow bug that keeps appearing in many of our social media feeds.

Simek, Environmental Interpretive Center Natural Areas manager, continues to walk the EIC trails on his personal time and says there鈥檚 no sign of them on campus 鈥 or anywhere near our state. 

He鈥檇 also like to put their real name out there 鈥 Giant Asian Hornet or Vespa mandarinia if you鈥檇 like the scientific name 鈥 because it 鈥渟ounds less sensational.鈥

Reporter chatted with Simek recently about the Giant Asian Hornet, along with some updates on what seasonal changes he鈥檚 seeing take place on campus as the grounds transition to summer.

Question: Do you have any concerns about the Giant Asian Hornet?

Rick Simek: My biggest concern is human perception of this insect and the confusion we may have with lookalikes in the bee/wasp world. Sometimes our perspective 鈥 if we have a certain association in our minds 鈥 overrides our ability for us to rationally interact with living things. Many people will group these insects together and it鈥檚 not good for us or the insects.

For example, if someone sees any bee or wasp that looks like V. mandarinia while picnicking or out for a walk, they might unnecessarily freak out 鈥 there鈥檚 so much going on in the world today and spending time in nature is one way to relax. We don鈥檛 need to bring additional worry into our lives over an insect that isn鈥檛 even here. I want to make sure people know that the nickname 鈥榤urder hornet鈥 doesn鈥檛 come from it attacking people and there is no evidence that they act overly defensive toward humans; they attack and kill helpful pollinators like honey bees. So let鈥檚 not turn on the bees over this; they have enough problems.

It鈥檚 not a secret that all kinds of bees, like the honey bee and the bumble bee, are extremely beneficial to us 鈥 their contribution saves us hundreds of billions of dollars in food production. And any gardener knows how helpful wasps can be 鈥 they remove unwanted pests. So please don鈥檛 react to the news of this invasive species by killing bees and wasps willy nilly. It鈥檚 important to remember that we share the world with other living things. Insects are vital to the functioning of our society and world. Birds need them as a food source. Bumble bees  give us wonderful fruit on our trees. There are so many ways everything is connected. A world without bees and wasps is much scarier than a problematic species.

Q: So we aren鈥檛 going to see them in our backyards?

RS: Not anytime soon, if ever. It's very fortunate that someone has already spotted V. mandarinia in what seems to be a relatively small geographic area along the northwest coast. This could prove to be critical in stopping its spread. We鈥檇 know if these Giant Asian Hornets have spread to the area 鈥 it鈥檚 relatively easy to because they will often leave dozens of headless honey bees at beekeepers鈥 hives. everywhere.

As with any new invasive species introduction, there is often a lag phase, which means that they need time to establish their populations before exploding onto the scene and causing substantial ecological and economic harm. I'm hopeful that the recent discovery in North America is within the time frame.

Q: Are you saying not to worry?

RS: Well, it鈥檚 not exactly ideal because they are an invasive species and our bee populations in North America, having never encountered them before, would be extremely vulnerable because North American bees do not appear to have adequate defense adaptations specific to the Giant Asian Hornet. Our concern should be for the bees and what happens if an invasive species doesn鈥檛 have anything in nature to stop it from destroying another. 

The news of the Giant Asian Hornet isn鈥檛 good. But the fear of them might be worse, especially during a time when we are all trying to stay well and find a bit of serenity in our lives 鈥 and one of the best places to look for that is outside.

Q: Speaking of spending time outside, what wildlife have you seen at the EIC Natural Areas recently?

There are so many new birds 鈥 every day you see something different. I saw a nice wave Eastern Kingbirds a little more than a week ago; they were stopping over in the Environmental Study Area on their way north after spending the winter in South America. And a Cooper's Hawk started building a nest right near an EIC entrance where school groups usually gather 鈥 these are fairly wary birds during the nesting season, so seeing them building a nest there was a reminder that things aren鈥檛 quite as they were before. Another sign that nature is getting a bit more elbow room: A baby mink was exploring a footpath that typically has a lot more human traffic. That was exciting to see.

If you see an interesting bird or animal when in the 51视频-Dearborn Natural Areas that you鈥檇 like to know a bit more about, take a photo and send me an email. I鈥檓 happy to identify and share what I know. We aren鈥檛 on the grounds like before, but the EIC staff is still available to help you learn a bit more about the creatures we share this planet with.

The EIC Environmental Study Area is  open daily from sunrise to sunset. When walking the trails, please follow Gov. Gretchen Whitmer鈥檚 orders on social distancing, mask wearing and small groups. Simek would also like to remind nature-goers that fishing on site is prohibited and to leave bikes and dogs at home because they cause disruption and stress to the EIC wildlife.
