Megarhyssa macrurus female. - 2 -- inspecting tree looking for place to deposit eggs
found on the huge river willows at Metcalfe Park in Almonte.
There were at least 3 of these walking up and down on the tree bark
about 3 meters above the ground. They were tapping their antennae
on the bark and would stop periodically then continue with their tapping.
One of them - the one in the 3 photos which I've posted, remained in
one area of the tree (approx 20 cm. x 100 cm.) for several minutes
and stabbed its ovipositor into the tree in more than one spot.
I managed to climb up the tree far enough to hold the camera up
at arm's length and shoot a few photos from various angles -- and
rather amazingly, some of them actually worked. (-:
