Crane Fly - Eutonia marchandi

Crane Fly - Eutonia marchandi
Amherst, Massachusetts, USA
August 19, 2004
Here's my shot of the large Tipula sp. Crane Fly. This one was resting on some potted pansies. They can be quite common up here in Mass.

Moved from Giant Crane Fly.

Limnophila marchandi
After study this image again, I realized that I have misidentified this crane fly. This crane fly is actually Limnophila marchandi , one of the largest limoniid species in North America. It does not have the pronounced velvet patches on the thorax as they are in Tipula abdominalis. My mistake. It is new for Bugguide and a new page is made for it. - Chen

Tipula abdominalis
As identified by Dr. Chen W. Young, (Assoc. Curator at the Carnegie Museum of Natural History) who runs the Crane Flies of Pennsylvania website.

 
field marks?
Did Chen mention any distinguishing characters? He IDed my specimen as T. abdominalis also, based on the thoracic pattern, but didn't elaborate. My specimen has a wide black band on the side of the thorax, and large oval "holes" on top - apparently missing in your specimen.
I'd like to add some descriptive ID info to the Guide page but don't know what to include.

 
Distinguishable characters
The two large crane flies in northeast USA are Tipula (Nippotipula) abdominalis and Pedicia (Pedicia) albivitta. Both species are distinct and can be easily tell apart by their wing venation. Pedicia with dark triangle mark on the wings, and Tipula (N) abdominalis with black velvet strips on thorax. Any other distinguishable characters are genitalia related and would need the aid of a microscope to observe - Chen

 
No field marks...
He didn't mention any ID markings Robin, perhaps you should email him...
