It was a real life outside shot, Bruce.
That is a rather uncommon species and the first time I have found one at that site. It was sitting quite still with the wings outstretched so I took a few images; but I really needed to see the wing underside to confirm identification. It wouldn't cooperate so I tried to gently persuade it to move, but it kept settling with only the topsides visible.
Then I tried another trick which has often worked for me. Ignore the subject and turn your attention to something else. After a few minutes I saw that it was now resting in the required side view position.
After getting the side angle, I thought I might as well try a fun shot as well. I took a few others from a slight side angle to show a bit more wing with the front angle, but eventually thought the straight on view worked best.
I've now looked at this image on my desktop monitor. It's a very good photo.
But it instantly made me think of tent caterpillars, which are frequently a real bane on our apple trees (as well as on certain other trees). So I looked up tent caterpillars as well as Lackey Moths on Wikipedia and saw that they in fact are the same genus, Malacosoma. Despite that fact, I like your photograph!
There are quite a few caterpillars who start their life by living in a group until big enough to fend for themselves.
Here is another caterpillar, a single living one. Mottled Umber moth.
I have let this first quarter of images go on for a bit too long so it is now time to start the second quarter. Maybe end up with having three 'quarters' instead of four this year?
