  1. Since moving to Montana from Illinois six years ago, this has become one of my favorite beetles, even though I’ve only ever seen two of them.

    I live in Oregon on five acres with a mix of farm/forest. I found this beetle in our dog’s plastic wading pool. I thought it had drowned as it didn’t move for two days. I scooped it out and put it in our mud room on a paper towel to dry out so I could take it to class I was teaching on garden insects for a summer camp, “Junior Master Gardeners.” After a night in the mud room, my husband called to me,” Did you know this bug was alive?” I ran to see and by gosh, he was moving his legs and antennae. My husband took him outdoors to see if he could survive 48 hours in the water and another 12 in our house, without food. Hope he made it. He was impressive!

      Insects are quite resilient. We have numerous postings of insects and spiders that have survive immersion in water on our site.

  4. Alb NM Each night after sundown, while I work in front of the garage. These seasonally cyclic beetles, Kamikaze dive into the pavement and struggle under the sodium light. I caught over 17 last night. The Desert Box Tortoises (we have five) absolutely love them. Crunchy outside, soft chewy inside. One waits at the door each morning, for it’s ‘meals on wings’. Even the 2″ baby turtle excitedly chases and catches them, even while buzzing their wings and hissing. :>)

    Thank you. We live here in Flagstaff Az. And have seen this hansom guy many times but I never new his or her name. We had a few make their way into our living room last night, I made hubby get the little guy to use its Velcro feet to stick to rag and carry him safely out doors. Thank you for answering my name question. I will use your site more often. Rose Hadden

    Just had two, frolicking under the streetlight over our driveway. My dog tried to catch one and seemed to get a mouthful of something he didn’t like, and it made him drool. He’s okay. Love the tufted antenna on these guys!

    I just found my 1st one on the cement driveway In Corvallis Montana,, way west in the Bitterroot Valley. My grandkids thought it was really cool, specially when it started pumping its wings and hissing at us!
