Squash Vine Borer

Dear Curious chick,
This is a Squash Vine Borer, a moth that mimics a wasp for protection against predators.  Larvae are borers in the stems of squash and related plants that can destroy a plant or drastically reduce its yield.

Hello! I would like to know the identification of this flying insect please? thanks!
Signature: Respondents choice. No preference.

American Hornet Moth

Though it is not a Wasp, it is an effective wasp mimic as the common name of the American Hornet Moth implies, and we believe we have correctly identified your individual, though a higher resolution image would be helpful.  According to BugGuide:  “In flight they closely resemble wasps, even producing the droning sound.”

Hello from Montana! I’ve seen these a few times, but rarely had I seen one sit still long enough to take a photo. Fairly large, the wings and body shape are particularly interesting… but what exactly is it? I apologize for the photo not being a tad more clear, I did zoom in after taking the photo, I didn’t want to get too close!

Cottonwood Crown Borer

Dear Margaret,
This is one of the wasp-mimic Clearwing Moths in the family Sesiidae, and we quickly identified it as a Cottonwood Crown Borer,
Sessia tibialis, on iNaturalist.  American Hornet Moth is another common name according to BugGuide where it states that the range is:  “Nova Scotia and New England, west to Vancouver, British Columbia, Rocky Mountains of Wyoming, Colorado and New Mexico, west to the Pacific Coast.”

It flies, it is the size of a large carpenter bee. I has a beetle like head ans wings that are orange, white and black that appear to attach at the back legs. His coloration is much like a monarch caterpillar on his body.

Glorious Squash Vine Borer

Dear Pauline,
This is one of the wasp-mimicking moths in the family Sesiidae, and we were lucky to locate the Sesiidae of Los Angeles County page on iNaturalist.  We believe this is a Glorious Squash Vine Borer,
Melittia gloriosa.  There are some nice images on BugGuide.  According to BugGuide it is also called the Manroot Borer and  “Larvae bore in the large tubers of various cucurbitaceous plants.”  Manroot is a native plant that is also known as wild cucumber.  The dried leaves in your one image appear to be the leaves of a manroot.

Manroot Borer

BINGO! Kudos Smile That is him, and that is also the dried leaves of the Manroot in the backyard.
Awesome! Thanks

Dear bugman,
I happened to notice this strange critter while at work today. I work at a greenhouse with flowers and vegetables. Unfortunately I could only get one picture of it before it flew away, rapidly. It has a shiny segmented body and a small, waspish head. The long orange “tail” also appeared segmented, and quite fuzzy. I have looked and found nothing like it on the internet. Please help? Thank you!

Clematis Borer

Dear Hanna,
Your description of this insect as “waspish” is spot on because this is a wasp-mimicking Clearwing Moth in the family Sesiidae, and we eventually identified it on BugGuide as a Clematis Borer,
Alcathoe caudata.  The binomial species name is thus defined on BugGuide: “Caudata from Latin caud, meaning ‘tailed.’ Adult males have a long tail-like appendage on the abdomen. ”  Your individual is a yellow-tailed male.  We have no other images of identified male Clematis Borers on our site, but we do have several images of female Clematis BorersBugGuide also states:  “Larva bore into the roots of Clematis and Ribes species.”  According to Las Pilitas Nursery, the genus Ribes includes gooseberries and currants and Clematis is a popular flowering vine used in landscaping in Youngstown, Ohio.  It is the end of the month and we are selecting your submission as the Bug of the Month for July 2017 because we are so thrilled to now have both sexes of the Clematis Borer in our archives.

Thank you so much! I’m glad that it “bugged” me enough to ask! Happy that I have also provided a useful photo, albeit a slightly blurry one!
Hanna B.

Western Poplar Clearwing

Dear Mike,
Your moth, a Western Poplar Clearwing,
Paranthrene robiniae, is a member of a family of moths that includes numerous individuals that are very effective wasp mimics, which affords them a degree of protection against predators.  You can verify our identification by comparing your image to images on the Moth Photographers Group and on BugGuide.  According to BugGuide:  “colored almost exactly like a paper wasp. Mostly yellow, first three abdominal segments black. Head is black, with yellow facial scales. FW orange brown with darker veins; HW clear with a deep yellow discal mark, fringed with dark brown scales. Antennae of males are bipectinate, simple in females.”   It should be noted that there is considerable variation in the abdominal markings of individuals pictured online.
