Flying Insect - Hartigia trimaculata - female

Flying Insect - Hartigia trimaculata - Female
Staten Island, Richmond County, New York, USA
May 20, 2009
Size: 1.5-2 inches
Is this a wasp or a flying ant?

Moved from Stem Sawflies.

Hartigia trimaculata (Say)
Female. Larvae bore in stems of roses and berries. Size varies, but can be very long; I think 1.5 - 2" would be the upper limit.

Definitely a male, whatever it is. Reminds me of a stem sawfly, but if the size estimate is correct (and not exaggerated), then it has to be something else, like a horntail.

this thing...
...looks the same as IDed by Dr Asher as cephid (a female, too -- just like the one here: in both cases the tip of the ovipositor is showing); and i do believe the size here had been grossly overestimated -- the perch suggests 1.5 cm, not inches

The size isn't exaggerated. It was at east 1.5 inches. That's why I thought it might be a wasp.

Is it a kind of fly???

Ants have "elbowed" antennae and these are quiet straight.

this is a cephid
I think it is a hartigia
