is this a Pigeon Horntails, Tremex columba???
This thing came flying in my house this morning and scared me and my dog! i grabbed the broom and killed it! then brought it to work to see if anyone had see anything like it before. no one had a clue. so i googled and found your website and after looking around the site, i’m guessing it’s a Pigeon Horntails, Tremex columba? can you confirm that? I live about 30 miles north of Houston in The Woodlands, Texas and I have never seen anything like it. Please let me know your thoughts.
While we understand how that long ovipositor can be off-putting, the Giant Ichneumon, Megarhyssa atrata, is harmless to humans. She uses the ovipositor to deposit her eggs in the burrows of wood boring insects, the larval food source. With all the recent publicity about Asian Longhorn Beetles possibly decimating our forests after arriving in this country in wood palettes, the Giant Ichneumons might be our only salvation. I guess your specimen will not be providing any future generations of pest control.
