identify hibiscus pest damage #872292

Asked June 09, 2024, 2:06 PM EDT

I have a hibiscus plant that has been reduced in size, a day at a time, by something chewing off the branches down low on the plant. It was about 3 feet tall and full of bright yellow flowers. It has been reduced to a bunch of 12 inch bare branches that are sticking up out of the pot. My first thought was it was rabbits. They tend to eat just about everything we put outside, but I have never seen anything chew off all the branches of a Hibiscus. Today, while mowing the yard, I found a tunnel in the long grass. I wasn't sure what it was at first, but I'm wondering if it's a groundhog. It's not a very big tunnel. So it can't be a very big groundhog. Also, one of my peony plants is all smashed down flat on the ground as well. Regardless what it is, if its going to damage my plants, i want suggestions how to get rid of it.

Without a photo to help me, my guess would be voles:

Habitat disruption is the best strategy.  Don't give them a place to hide.

Hello.

First of all, thank you for your first reply.  I know it was difficult to visualize my types description.  I did go out and try to get a few photos on my phone, but when I got outside,  I noticed my phone was out of battery.  Since I had the email typed up already,  I went ahead and sent it.   Since then, I did get some photos to show you.  There are several photos of the hibiscus plant trying to show you the way the branches looked after they bit off by whatever animal did this.   If it's rabbits, I don't understand why suddenly now they are destroying my hibiscus plants.  I have been putting my hibiscus plants out on the deck for the past 20 some years.  Never has anything tried to eat them. 

As for the hole in the backyard,  I went back and cleared the long grasses away from the hole and I pushed a stick down into the hole, and it didn't go anywhere.  Its just a hollowed out area.  My guess is its an abandoned rabbit nest.  There is one photo attached of the hole as well. 

thank you and I hope its still OK that I'm responding to your first reply.  It looks like the status on the question shows "closed".   Hope this still gets to you.

I do have one other question on an insect that keeps hanging around my

front door at night. I recently had a doorbell cam installed and

periodically over the past 3 weeks, there has been some type of insect

that keeps showing up on the cam. The first video clip was this critter

crawling along the top of the video. You can only see the legs. It

almost looks like big spider legs. Second video shows a much better

view. I can't be sure but from the photo, I was wondering if this is

some type of moth?  It's only there later at night in the dark. Seems

to be attracted by the porch light. That's a strong characteristic of

moths, but when you see the body, it has striping coloration that looks

like a bee. It doesn't give a good view of the wings, but you can hear a

strong buzzing sound, so I'm thinking it's those clear wings that make

it sounds like a bee. My grandkids think it's a wasp. It looks quite

big in the video, but I'm wondering if the curvature of the camera lens

accentuates it's size. Is it possible that someone there could identify what type of insect this is?


I just tried to attach the video clips, but it won't let me select them.   Does this messaging software not allow videos to be attached?   How can I send these video clips?  They are saved on my downloads folder as MP4 files.

My guess remains rabbits.  Why they decided after 20 years that your hibiscus is now the thing to eat, I don't know.  They do that, though. And that hole is a rabbit nest.  Just to cover all my bases here, look under those pots for slugs.

As for the flying insect, I'd request that you send this as a separate question.  Keeping to a single topic helps us in two ways. We can direct the question to the proper expert, and it helps search engines finding the proper answer.
