First up is a male tree cricket (Oecanthus sp.). It was singing near our back patio, but shut down the moment I showed up. It may be the snowy tree cricket (they are out there), but a key way to distinguish that one from a couple look-alike species is to get a good picture of the base of the antenna from the front. I keep forgetting to do that.

Next is a very small geometrid moth that is commonly known as the “bad-wing” (Dyspteris abortivaria), apparently because its delicate wings make it very hard to mount in collections.

The planthopper shown next is Acanalonia conica. These beautiful insects are amusing to photograph. When they realize they are being watched, they deviously move to the back of the twig. The trick then is to put a finger behind the twig, and that makes them sidle back to sit in plain view.

Finally, here is a little tree frog. It could be one of two species that are around here, either Hyla chrysoscelis, or H. versicolor. These are identical in appearance, although their songs are different. Interestingly, the 2nd species is tetraploid, meaning that it has a double set of chromosomes.

Thanks for looking!

Great set Mark. Love the way you've captured the wing venation. Fine work my friend.

Super images and interesting about the chromosomes. I wonder how many people unknowingly have double sets, it could account for some unexpected behaviours I suppose.

In humans, the condition (called polyploidy) is fatal and results in early miscarriage. But it is successful in plants, and in various groups of animals including fish and amphibians.
In plants, polyploidy results in larger size, and so polyploid plants can have advantages. Humans have been selectively cultivating plants for millennia, and in several cases what we selected for were polyploid plants.
Ok, I'll stop now.

No need to stop Mark, I find it really interesting so thanks for the reply. I will go and learn more about it now.
