Bug [updated III]

Christine found a very cool bug on the veranda. Even cooler close up:



Closer upper:



Click to enlarge the photos and really see the amazing patterns, especially in the one exposed wing.

And a little video, to show the brilliant orange, if just for a second, under its wings:




I'll try to find out what it is. Reminds of an Oregon bug we used to call "f*ck bugs," because you'd so often see two of them flying around in flagrante. (Those ones are box elder bugs. That ought to help me find them.)

Update: This is very fun. Because they look like box elders, I googled the genus of box elders, Boisea, with "Australia." I got nothing, in both "web" and "images". So I moved back on the taxonomical ladder, to the family, Rhopalidae. I got this:



You can see especially in the bug on the right the similarities in the triangular wing cover patterns, and especially in the big wing sticking out—clearly just one wing visible, giving it a one-sided look—just like our bug. So I think I'm on the right track.

Update II: Closer...

Update III: Almost there:


That's it! It's the Eucalytus Tip Bug, Amorbus alternatus. Success!

They have lots of other names, apparently, including squash bugs, and come in a variety of colors.

And check out this sentence:

Scentless Plantbugs in Family Rhopalidae are closely related with Coreidae but lacking well-developed scent glands.

Coreidae is the family of our bug here, and it's closely related to the Rhopalidae family I used to search. So my internet sleuthing technique worked!

  1. Isn't the Net wonderful for critter ID'ing? We have a bug that's very similar to this here in Ashland. It's browner and a tad more "armored" looking. And...when you disturb them they emit an awful smell that's sort of like camembert cheese that's been left in the sun for a couple of days! They make a distinctive "ripping" sound when they fly. The weird thing is that there are certain years when they're quite common out in the park and other years when I don't see nary a one. I know that "ripping" sound though, and when I hear it I'm careful not to do anything but gently blow them off me if they land.
