Large Giant Ichneumon - Megarhyssa macrurus - female

Large Giant Ichneumon - Megarhyssa macrurus - Female
Lakeland, Polk County, Florida, USA
April 17, 2013
Size: Body - 53 mm
This female giant ichneumon is the first I have seen in Florida, much less Polk County. It was brought to me by a student at my school. I photographed it at home. Antennae to end of ovipositor is greater than 6 inches. An incredible specimen and wasp.

Size
The size evidently precludes the possibility of it being greenei floridana, which contrasts with the nominate subspecies in having the wings almost uniformly dark brown. As in most of their revisions, the the Towneses provided only measurements of forewing length of species of Megarhyssa. I note, however, that the similarly colored specimen from Lafayette Parish, Louisiana, which was measured at 35 mm. I have that specimen and confirmed at as Megarhyssa macrurus, and your specimen is significantly larger than that one.

Yup, they're impressive.
I see them fairly often in my area. They're certainly impressive.

Incidentally, could you delete the date "December 31, 1969" and replace it with the correct date if you know it? Thanks.

Please click on "edit"...
...and fix the date on each image--unless, of course, it was actually photographed on December 31, 1969. :)

Thanks.
