Yesterday was International Rock Flipping Day. I’ve read about it in the past, but this is the first year I’m participating.
I don’t really need an excuse to flip a rock and explore what’s beneath, but the whole event certainly motivated me to get my blog posts going again. IÂ haveÂ been busy outside of blogging, so there’s plenty of good stuff coming up, so don’t give up on me.
Yesterday was beautiful here in my area, so I already had plans to go bug hunting. Knowing I’d be looking for a rock to flip, I chose a nearby park where I knew there were lots of good candidates. Here’s the rock I settled on after being distracted by lots of other interesting critters along the way.
Being National Moth Week, I have every excuse to post about one of my favorite subjects. Admittedly, I get more excited about caterpillars, but I enjoy seeing the moths that most of them become.
Back at the end of April, I was distracted by something while going to check the mailbox. Actually, I’m often distracted any time I venture into my yard, but that’s kind of the point of having one for me. Anyway, some large hollies form a hedge along part of my driveway. I spotted a caterpillar dropping from from the holly to the ivy beneath it. I grabbed it for a closer look and started scanning the holly for others. I quickly found another one and brought them inside for rearing. Less than a month later, I was rewarded with a Black-Dotted Ruddy, Ilecta intractata.
Arikok National Park contains the most well known of Aruba’s caves.Â I visited one of them, Fontein Cave, guided by a park ranger.
Arawak indians inhabited Aruba around 1000 AD. They adorned the walls of this cave and others with petroglyphs.
At the park’s visitors center, a display suggested that the following petroglyph might be an ironclad beetle.
My guide quizzed me on a few others. I was asked about this one first.
I guessed honeycomb. My guide smiled and vigorously nodded.
Bees were definitely on my mind though. I had just seen a bee hive in the limestone not far from the cave entrance.
The Striped Anole,Â Anolis lineatus, was probably the species of lizard I most encountered in Aruba. I assume the common and scientific names refer to those dark broken lateral stripes, but it’s known locally as Waltaka.
Here’s another one, a female perhaps.
My earlier post of the lizard on a tree is also one.
After a good bit of googling, I came across a good free resource on the reptiles and amphibians of Aruba, link below.
Here’s yet a different species of colorful treehopper. These too were found in association with ants.
While hiking around in Arikok National Park, I spotted from a distance some bats flying around below a small limestone overhang. I approached just close enough to snap a few pictures for possible identification.
I’m not nearly as close as this picture might suggest. I used my 100mm macro with a 1.6x teleconverter. This is also a significant crop from the original photo.
It appears I may have upset them, although I didn’t know that at the time. I’m surprised by their reaction. I didn’t figure my activity would disturb them. They weren’t in a cave, just beneath an overhang where there was plenty of indirect light. They were restlessly flying around even before I approached, perhaps trying to find a dark corner.
I had planned to post just a single photo of this scene with ants tending treehoppers. Here we see at least two different colorful treehopper instars, with one actively molting. Ants like the one shown above tended to this small grouping of treehoppers.Â As I was choosing a photo to post, I noticed something strange about the treehoppers though. Do you see it too?
Look closely and you’ll see that a few nymphs have parasites. I wasn’t sure at first, so I started looking through my other photos. Sure enough, almost every one had one or more parasites. The parasites seem to prefer hiding under the wing pads and below the thorax.
On the underside of a leaf, an attractive lynx spider guards her egg sac.
Aruba could easily be called “Lizard Island”. You can’t take a step without seeing a few scurrying away. I don’t think there’s a square inch of sand that doesn’t have a lizard track in it.
This was one of the last caterpillars I collected last year for rearing. I generally stop looking around the end of October.
This particular caterpillar is fairly distinct and easily recognized as Schizura ipomoeae. The stripes on the head capsule are diagnostic.
The adult on the other hand is more difficult to recognize, I think. I’d have probably given up identifying it if I didn’t already know what it was based on the caterpillar. This particular one emerged in early May.
You might have noticed I haven’t posted anything in awhile. I get a lot of enjoyment from posting here, and I remain committed to doing so whenever possible. Lately it just hasn’t been a priority for many reasons. Hopefully, I’ll now be able to get back to posting more regularly.
