Feather horned Longicorn (♂)

Piesarthrius marginellus


About 25mm body length. Nice feathery antennae which it could actively open and close. Last pic is after it finally jumped to my tee shirt so I wore it for another 30 mins :-) These cerambycidae are getting interesting.


Initially in a used car yard at night on the roof of a Ford Focus..


(Last photo by Leuba because I'm no good at selfies) order: COLEOPTERA
suborder: POLYPHAGA
tribe: Strongylurini
genus: Piesarthrius

That camera repair seems to have been hanging about for while?

Thank you DrNamgyalT.Sherpa. Luckily it was very cooperative and I'm still awaiting repair of my other camera. :-(

@Lauren I was pleasantly surprised to them open/close. It seemed to respond to my presence/threat ? On close inspection I guess there could be a muscle in each of those little swollen antennal segments. We found another one last night but couldn't get him to open his feathers.. just not in the mood I suppose or maybe a headache :-)

Congratulations Mark! This is one very gorgeous beetle. Great series! It must be so much fun to see it alive and see the way it moves the antennae. I wouldn't have suspected they could open and close the feathery extentions.

Thanks Sergio, Adarsha, Sckel ... all Aussie males need and own thongs... but we're trying hard to give up the high-heels.

Fantastic beetle, congratulations again. yes, he's ready for Mardi Gras, since males do not need thongs and high heeled shoe. :)

Way to go, Mark, congrats. Yes, it is a huge task to get all those beetles, but think the other way around, you'll hardly come back home without one or two spottings... :-)

Thanks Jolly Martin, Tina. I wonder how hard it would be to make jewellery like this.

Oh Mark! Happy that you got the honor, especially after carrying it around for 30 mins :) It happens to be very cool, so you did the right thing! Hurray for you and your Horned Longicorn today!
