Horse Fly Exuvia, we believe

Horse Fly Exuvia, we believe

Hi again KyLee,
We already wrote back that this is the exuvia or cast off exoskeleton, but we were not sure of the species.  It sure looks Dipteran, or fly-like to us, so we continued to research.  We found this very similar looking exuvia on BugGuide that is identified as being from a Horse Fly.  We are pretty confident your kids found the exuvia of a Horse Fly.

Wow! Thank you so very much. I knew you folks could help us. Now we will look up the horsefly and study it.  I truly appreciate your time and effort.

    I found an exuvia in my yard last weekend, 6/24-6/25, in Port Elizabeth NJ. It is almost identical to the images posted here, more similar than the image on bugguide. This exuvia is huge. Close in size to a cicada exuvia. I think it unlikely to be a horsefly.

    And a know positively that it is not cicada, i only mentioned that to give a size comparsison.

    The exuvia 1 5/8″ long and 7/16″ wide.
