One of our early morning landscaping projects has been keeping us busy shoveling our way through 14 tons of pea gravel, one wheelbarrow load at a time. As each backbreaking load is hauled into our back yard and dumped on miles of weed barrier fabric, we keep reminding ourselves how nice it will be when Luna no longer returns home with muddy paws.
What began as a daunting pile of millions and millions of tiny little stones, by morning #3 the pile still looked impossibly huge, while the only thing diminishing was our enthusiasm. So it wasn’t a big surprise when, after only 15 minutes of scooping, a very large and shiny black beetle was welcome excuse for a break! After all, she was charging across our travel path, and without rescuing would’ve surely been squished flat under a careless wheelbarrow tire!
And we paused …… for nearly 45 minutes ….. as we ooohed and aaaahed over such a magnificent beetle, wondering what she could be. Well over an inch long, we noticed her blue-black head, thorax (pronotum) and hard wing covers (elytra) as shiny as freshly polished paten leather shoes, were ringed by a dense fringe of rusty orange hairs. When she went belly-up, we could see those hairs all over the ventral (lower) side of her head and thorax.
Not enjoying exposing her undersides to the world, those six flailing, long and powerful, many-segmented claw-tipped legs flipped her body over and she quickly resumed charging across the ground. Roy kept her in sight while I ran for the camera, determined to take lots of photos to get an ID. About a dozen poses later, and with the help of iNaturalist, I learned that our visitor appeared to be a female Western Rhinoceros Beetle (WRB)!
Yes, apparently there are Rhinos in New Mexico! How cool it would be to find a male or two, and watch how they use their horns (which are as tall or taller than their steeply pitched and somewhat concave pronotums) in battle to win a hornless female.
Wonderings! Why was our female WRB in such a hurry? Was she running from a male? Two battling males? Had she mated already and was in search of a Velvet Ash Tree (a NM native species and likely her preferred food source) where she could lay her more than 100 eggs in the soil beneath the tree? How does she find these ash trees, because I’ve never seen one on our 2 acres or along any of our neighborhood hiking trails?
So many unanswered questions! But you can bet I’ll be on the lookout for the next WRB to trek on by. Maybe I’ll drop everything I’m doing (like scooping pea gravel) and follow her or him just to answer a few questions! Do you think Roy will mind being left behind holding the shovel?
As always, thanks for stopping by!
