Horntail - Tremex columba - female

Horntail - Tremex columba - Female
Atchison, Atchison County, Kansas, USA
September 27, 2009
Size: 1 1/2 inch
It's behaviour was very odd. I could touch it (accidently did) and she didn't move away. Her lower area with the depositor was moving like mad all over....I video recorded her and re-watched the movements. It didn't seem like she was trying to find hosts to lay the eggs.
Found on a Maple tree covered in Reishi fungus. Any ideas?

excellent photo -- thanks!
'Sauria' is an old sci. name for the Reptiles -- any connection?

Moved from ID Request.

Horntail
Incredible! Just when I think I THINK what it is...it's nothing of the sort. lol
What an amazing world this is. My Explorer isnt' working for some reason but once it does I'll look up all the info on this insect.
I'm wondering now if she was laying eggs in the wood or???
This WAS a 'she' right? (let me be correct about SOMETHING here...lol)

Horntail
They're not parasitic and cause no harm to the trees they lay their eggs in. This one Is a female! They're actually friendly, I've kept one before! They're unable to sting with the ovipositor! They only lay their eggs in already damaged trees. really nice picture!

Very neat creature. I touched
Very neat creature. I touched her a couple times when I realized she wasn't aggressive. I had recently come into contact with an Ichnedea wasp and was thinking she was one of those because of patterns and her ovi-positer.
The tree she was on was definately having a fungi issue...so I'd figured whe was looking for the bugs that were feasting on them. Now that I've the info, I know she was probably trying to find softer areas to lay the eggs in then. Thanx Breanna!
