What is this Orange, Yellow, Black bug?
October 31, 2009
Flying insect found in Anne Arundel County, MD. Size =0.75 inch. Wing span compact (delta shape) about 1.25 inches when extended. Dark wing veins. Head and feet black. Abdomen yellow/orange and appears “fuzzy”.
Currently swarming. Swarms appear to be mating and are found on top branches of euonymus bushes (our Burning Bush was decimated by caterpillars this spring, could this be the same insect?). Never seen this variety of bug in past 12 years in this area.
Anne Arundel County, MD 21146

Unknown Sawfly? or Moth???

Unknown Sawfly? or Moth???:  Leaf Skeletonizer Moth

Hi Peter,
We really wish your photograph was of a higher resolution as it is impossible to make out any details on your infestation.  We found information on a Euonymus Caterpillar, Yponomeuta cagnagella, but the photos of the moths on BugGuide look nothing like your insect.  We also located a pdf (euonymus_A3633) on the same species.  We believe your insects look like Sawflies, but again, there isn’t much detail.  We have not had any success locating information on a Sawfly that uses Euonymus as a host plant.  If there was a caterpillar invasion in the spring, and sawfly larvae are often confused for caterpillars, we suspect these adults might be related.  We would not rule out moths, but we suspect these are Sawflies.  Perhaps one of our readers will be able to assist in a proper identification.

Eric Eaton Responds:
Oh, man….My first thought is “aphids,” actually, or maybe psyllids?  Might try sending this to the Ent Dept. at University of Maryland in College Park.  They will probably recognize it right off….

Bagworm Moth Perhaps

Our identification request:
Dear Drs. Mitter, Kent and/or Hawthorne,
My name is Daniel Marlos and I run the highly unscientific, pop culture, insect identification website What’s That Bug? at www.whatsthatbug.com on the web.  Today I received an image from Maryland that has me perplexed.  I thought perhaps a sawfly or even a moth like a Bagworm.  Eric Eaton has suggested possibly an Aphid or a Psyllid.  The insect is swarming on Euonymus and there were caterpillars on the same plant in the spring.  Can anyone provide an identification?  I realize the photo is of very low resolution.
Thanks for your time.  Here is a link to the posting:  2009/11/02/sawfly-on-euonymus-we-believe/

Bagworm Moths Maybe

Thanks for the reply.  I’ll have to work on getting a camera that can do close-ups.  I looked at the sawfly photos on Google images- not even close. The bugs in my yard have dark heads (black) and fuzzy (furry) bodies.  No saw extending out the back of abdomen.
The antenna are very long and branching like those of a moth.
The head and legs are black.  The wings translucent with black veins and a black hue. The abdomen is bright yellow-orange and fuzzy.
I’ve tried to take some additional photos (bugs out side are rather sluggish in the cool weather), but I still lack close-up lens to really get detail.  I’ll send these in separate e-mails since they are rather large.
Look forward any further thoughts you may have.  They are a very unusual and quiet beautiful bug….

    I definitely have these in my yard also! They are swarming all over, but they seem to hang out around this one bush I have and my porch, mostly. I’ve never seen them before this year (in Anne Arundel County too). I’m interested in seeing what anyone comes up with for this, because they are everywhere.

    I have these same bugs hanging around the shrub by my front door. I also live in Anne Arundel County. Are they dangerous? I can’t seem to find any information on them online. Above it says it’s a new species. Could we get some more information about them?
