Clearwing

Lesser Peachtree Borer

Hi Chelsea,
Though it resembles a wasp, this is actually a Clearwing Moth in the family Sesiidae, and many members of the family are effective mimics of wasps, a physical attribute that acts as protective mimicry.  The defenseless Clearwing will be avoided by many predators who have previously been stung by wasps.  Many Clearwings look similar, and we will attempt to identify your species later today as we now have some house keeping to which to attend.  You can see many examples of Clearwing Moths on BugGuide.
  Though we at first claimed we would attempt a more thorough identification later, we decided to give it a quick try, and we believe this is a Lesser Peachtree Borer, Synanthedon pictipes, based on images posted to BugGuide where it states:  “Larvae tunnel under the bark and in the twigs and branches of cultivated and wild peaches, plums and cherries (Prunus), Amelanchier, apples (Malus spp.) and pears (Pyrus) (all Rosaceae).”

Hello, I found this in my garden. I’ve never seen anything like it before. Do you have any idea what it is? It is about 3/4 of an inch long.

Hi David,
We just posted another image of a Squash Vine Borer earlier today.  Your image is interesting in that it contains the exuvia of the pupa, indicating that your individual just emerged as an adult.

Hello,
Well I looked at many websites to identify this orange and metallic blue wasplike moth I’ve recently seen on potato plants, but no luck! The leg uppers are heavily furred while the lower parts are black with white rings. The rear legs are heavily furred the entire length. Wings are slender metallic blue-black. It flies fast but can also hover. This picture was taken in Stittsville, Ontario on June 21, 2014. Thanks in advance for looking!

Squash Vine Borer

Squash Vine Borer

Hi Claude,
Do you also have squash or pumpkin plants in your garden?  This is a Squash Vine Borer,
Melittia cucurbitae, a diurnal species in the Clearwing family Sesiidae, a family that includes many species that mimic wasps very effectively.  The larvae are borers that will severely compromise the health of plants in the squash family Cucurbitaceae by boring in the stems.

Thanks so much for the ID!  Of course, yes I had squash vine borers last year on my squashes- I completely forgot what they looked like.  Thanks again, I’ll keep an eye out for the eggs and damage.  Last year I buried the squash leaf nodes which helped root the plant along the ground.  Nevertheless, there were a lot of very large grubs in the stems which were needled to kill them.
Cheers,
Claude

Saw this guy on my squash plants, we’re having a hard time keeping bugs from demolishing our garden without resorting to pesticides so we try to remove them individually. This little guy was just relaxing on a leaf and didn’t appear to be doing anything destructive and relocated to our corn to again just hangout it appeared. Any thoughts on what it is? Our google-fu is pretty weak bug wise and we got nothing that way.

Hi Dave and Kara,
If this Squash Vine Borer, a moth that mimics a wasp, lays eggs on your plants, her progeny will bore in the stems, compromising the health of your squash plants.  This article from The Urban Garden might provide you with some helpful tips.

Thanks! We’ve got some neem oil and orange oil to try and I got praying mantids today hopefully they’ll take care of them, I’ll definetly give the article a read!

Hello!
I found this bug outside on my truck. I have never seen anything like it before. Do you know what it is?
Thank you!

Hornet Moth

Sycamore Borer

Hi Lucille,
Your insect is a moth in the family Sesiidae, the Clearwing Moths, and many members of the family, including your individual, are excellent mimics of hornets and wasps.  Your individual resembles the American Hornet Moth,
Sesia tibiale, which is pictured on BugGuide, however, we cannot say for certain if we have correctly identified your individual as the American Hornet Moth.  Your individual appears to have some yellow scales on the wings and there is a tufted abdomen, features that appear to be lacking in the American Hornet Moth.  We continued searching revealed a much better match, the Sycamore Borer, Synanthedon resplendens, which we located on The Moths Photogragher and then verified on BugGuide where it states:  “Larval hosts: prefered – Platanus racemosa (California sycamore); also used – Quercus agrifolia (Coast live oak); occasionally avacado.”  The larvae are wood borers.

I was outside tending to my raised bed vegetable gardens last week when I encountered this fascinating bug. It hovered over my yellow squash and cucumber plants several times so I was able to grab my camera and get at least one good picture of it. I’ve never seen anything like it so I’m curious to know what it is and if it is a beneficial garden predator.

Dear PlanetZoo,
This is a Squash Vine Borer, a moth that mimics a wasp.  The larvae bore in the stems of squash and other related plants including cucumbers, so we have to go with foe in the vegetable garden.

Thank you ever so much for your quick reply and help!
I have much to learn yet about the fascinating world of bugs and veggie gardening, as well as how best to navigate your invaluable website!
Hope you have a great day.
