I Entered a Contest

Several months ago, while reading a photography magazine, I came across the announcement of a contest. I looked at the handful of photos that accompanied the announcement and thought, "I can do that." This was not a local or even national contest. It was the global Close-up Photographer of the Year (CUPOTY 6). I paid my euros soon after seeing the announcement. Then my confidence waned and I had a hard time choosing pictures to submit. I didn't submit my pictures until the day after the deadline, and I'm not even certain they were accepted.

I entered in the insects category. The "shortlist" has been published, and I can see why my pictures did not receive a mention. The great majority that made the shortlist are beyond my capability. Here are the pictures I submitted. I've posted most of these before.

Monarch caterpillar (2019). I chose this photo for its action: Did the caterpillar cause the stem to break?

Honey bee (2019). This one pleases me. The background is clean and the angle makes the image more interesting.

Black swallowtail caterpillar (2024). I chose this because of its simplicity.

I chose this because of the unexpected perspective.

Long-legged fly (2024). I chose this for the slightly low angle and the wave of the leaf's edge.

Honey bee (2024). I chose this for its artistic nature.

Some Bugs

The Missing Gardener's plants and the neighbor's cherry tree have attracted bugs this year. I used a macro lens for all shots.

Bicolor striped sweat bee. I hope I see it again; I need better pictures. July 24: I did see it again.

I use the Seek app from iNaturalist and Ohio Department of Natural Resources field guides to identify bugs. I use the Seek app and the Missing Gardener to identify plants.

Focus Stacking Artifacts

The focus-stacking software I use can introduce artifacts into images.
 
Sometimes a "reflection" is generated. Here, there's one across the bottom. (Check out the crablike spider at the top.)
 
As I was shooting this caterpillar, an ant made its way along a lovage stem, and focus stacking gave ghost ants. There are reflections at the top and bottom, too.

Without ghost ants

When I shoot macro with focus stacking in mind, I set the lens to the closest focusing distance and then approach the subject until just before it's in focus. Then I shoot a burst as I move the lens closer.

I wanted the bug in addition to the bee. The bug was closest to the lens, so for the focus stack I chose an image with the bug and then skipped some images until the bee was in focus. The result is a semitransparent effect. This happens somewhat often and I haven't figured out when it's likely.


Without the image of the bug in-focus, the bee is less ghostly.

To get the picture I wanted, I took the previous image and pasted-in the bug and parts of the flower.

Recent Bugs


A fly? A bee? I put less effort into identifying the types of some insects than I used to because there are flies that look like bees, bees that look like flies, flies that look like wasps, and I don't know what else. As for species, sometimes it seems as though one has to count the hairs on a leg to decide.

 A northern paper wasp, maybe. Many photos show them with stripes, but this photo matches one in an ODNR publication which says, "This is our most common native paper wasp, but is highly variable and can be mistaken for several different species. Further, recent studies have revealed two previously unrecognized species nearly identical to the Northern Paper Wasp." Also, an Iowa State U. website says, "... the separation of P. fuscatus from related species remains the greatest taxonomic problem of the northeastern Vespidae fauna." What did I write in the first photo's caption?

cabbage white butterfly, I think. This would have been a fantastic shot if only the butterfly were in focus.

Leaf-footed bug. I focused on the eggs, which look like barrels lined-up end-to-end. The party is on a porch screen.
