Hi Jack,

There are (3) species of genus Anthopotamus present in MO, A. myops, A. neglectus neglectus, and A. verticis. In my opinion, your photo can not be reliably identified to species level, so I am placing it in the guide at genus level.

Incidentally, a body length (as measured from the front if the head to the end if the abdomen, not including tails) of 1" would surprise me, as the female imagoes, which I believe yours to be, would be expected to measure ~15 mm, ~9 mm, and ~9 mm, respectively.

It also strikes be as somewhat unusual that an Anthopotamus would be emerging in early October, as their emergence period is usually listed as June through August.

Please advise.

Thank you Roger
After thinking about the size I may have been wrong about that. But the date is correct, it is recorded automatically with the picture. We had very unusual weather here in Mo. this year, early spring, late frost, drought, and now a warm fall going into winter. So the weird weather might have played a role in the late hatch. Thanks for your input, I appreciate it, and I will pay much closer attention to details, body size, etc. in the future. I'm new to this and have everything to learn. Input like yours will help me.

check out Anthopotamus neglectus... cool stuff at your porch!

Thanks again!
That sure looks like it. Thank you.
