This critter was in our garden when I walked Thor this morning; then he rambled up to the AC for a nap:

After realizing how much I was hearing this year I had heard last year in St. Louis and forgotten, I decided to write a few things down.

Art

Simplify. Simplify. Simplify.

Get low.

Use a polarizing filter to get rich colors in landscape photography.

Biology

Some ants have stingers, not just fangs.

Toads have been recategorized. There are no more Bufos left in North America!

Butterflies aren’t even a clade. They’re just different families of moths that have evolved along similar lines.

The problem with photographing insects in New York is that I get maybe 4 good months, and then it’s back to birds for 8 months. By the time insect season rolls around again, I’ve forgotten what I figured out last time. So once and for all, let me write this down.

FYI, these settings are all for relatively stationary insects and a 1:1 100mm macro lens. Butterflies and dragonflies (i.e. large flying insects) with a telephoto lens are something else entirely.

Daytime, no flash

• f/8, maybe f/11 for deeper insects
• shutter speed 1/400 s or faster
• ISO 400-1600 as necessary to get the shutter speed up.
• Check your histogram

Consider using a tripod, cable release, and/or reflector.

First of all it’s Tuesday, and second of all this is a Sachem Skipper, which, depending on whom you talk to, isn’t a moth at all, but rather a butterfly (or maybe not–read on). However the real moths are getting rather thin on the ground around here as winter approaches, and unless I take a trip to warmer climes sometime soon, Moth Monday may have to go on hiatus until Spring.

However the real taxonomic story is a little more complicated. Perhaps noticing all publicity the American Museum of Natural History got by demoting Pluto from planetary status, the Los Angeles Museum of Natural History put up signs in its live butterfly and moth exhibit telling visitors that there is no scientific difference between butterflies and moths.

Moths are getting a little scarce around here right now, especially on a cold rainy weekend like we just had, so here’s a Straight-toothed Sallow caterpillar from a couple of summers ago at Ridgewood Reservoir recently identified by Tom Murray:

Straight-Toothed Sallow, Eupsilia vinulenta, Hodges #9933
Ridgewood Reservoir, Queens, New York, June 9, 2007

I’ve never seen an adult, but you can see some pictures at BugGuide, Butterflies and Moths of North America, and the Moth Photographers Group.

Chickweed Geometer was one of the first moths I posted here, but these days I have much better camera equipment:
