Acanthocephala femorata, I think
Hmm. Sure looks like Acanthocephalus femorata, Slater, fig. 89. (1) The common species I've seen here A. terminalis, apparently. It doesn't have those big "pumped up" tibae, just leaf-like thingies. See Troy's photo of presumptive A. terminalis:

I'm not seeing any convincing images on the web to show you, but the illustration in Slater is a perfect match.

Nice photo, as always.

No, sorry:-)
Right family (Coreidae), but this is Euthochtha galeator, male. They are much smaller than the Acanthocephala species, and lack any expansions on the hind tibia ("shins"). Troy's image IS an Acanthocephala.

Thanks (as always) Eric,

I made a quick guide page and moved the image. Anyone feel free to add to the information about this species...


Thanks for correction!
Yup, Euthochtha galeator, 15-17 mm is Slater, fig. 97, a couple of pages after Acanthocephala femorata, 25-28 mm. I am beginning to see the light. I see the shin thing. Thanks.

Thanks Patrick,
Thanks Patrick,

I'll do some snooping around and see what I come up with:)
