Creatures That Saw The Light, Part I....

 ...and came to check it out! Of course I am talking about black lighting, mainly for moths, but also for whatever creatures of the night are drawn to the brightly lit white sheet. It is always amazing how these interesting critters respond to the wavelengths of light that are not as well seen by humans. Just another fascinating aspect of nature!

Moore Wildlife Area is a fascinating area more or less in central Lambton County, owned/managed by the St. Clair Region Conservation Authority. I had the privilege of setting up my black lights there on three different occasions this year. A couple of times were just from the parking lot, but that is pretty good in itself. In fact I found the first Canadian record of a moth there last year, right at the parking lot. 

With the Sydenham River traversing this wildlife area, and this river is well known for rare aquatic species, I did set up on one occasion right along the edge of the river, which included an overlook of the river and had good visibility to the woodland as well. I came across, and photographed, well over 100 species of moths, as well as a variety of non-moth species. Some moths were rather worn and difficult to identify, so the totals may increase as people much more expert than I am, eventually identify them on iNaturalist or Bugguide. At any rate, what follows is a few of some of the more colourful or patterned moths. They are shown in alphabetical order based on their common name.

I thought this first one, an American Idia, was really nicely patterned and showed well on the piece of wood that it came to visit nearby. Not all moths land on the white sheet, but may land on a nearby tree or even on the ground or grass.


Arcigera Flower Moth

Close-banded Yellowhorn

On the evening I set up by the river, the midges were quite abundant. It was sometimes hard to get a photo of a moth, such as this Common Lytrosis, without being deluged with midges!


Common Spring Moth
This next one is probably a Crocus Geometer. There is another one in that complex that is sometimes difficult to separate, and some moth-ers lump them together. But I think this one is pretty colourful and relatively distinctive with this pattern.
I always like seeing this next one come in to the light. It is delicate, as its name states, and the golden yellow edge to the wing and the head is quite attractive.
Delicate Cycnia

Dimorphic Macalla Moth

Fervid Plagodis

Green Leuconycta

Gray Marvel
You have likely all seen those Woolly Bear caterpillars crawling around late in the season. Well if they survive and turn into adults, this is what they will look like, and are known as the Isabella Tiger Moth.

Julia's Dicymolomia

Lappet Moth

Large Maple Spanworm

Least-marked Euchlaena

Little Virgin Tiger Moth
This next one is very small, as you can see by the nymphal form of the midges in close proximity. It is the Metallic Casebearer.

Oak Leaf Shredder

Pearly Everlasting

Pink-barred Pseudostrotia
The Silk Moths always garner attention, and are a highlight to have come in to the light. This one did come in to the light, but eventually landed on the grass, and then for the longest time, clung to the bottom of a nearby tree. It is a Polyphemus Moth, and one of the largest of the large silk moth group with a wing span of up to 15 cm (6").

Red-fringed Emerald
The Papaipema genus is fascinating, and fun to try and figure out. It was a member of this genus that I photographed in 2019, that turned out to be the first record for Canada. The one shown next is more distinctly marked, and is known as the Rigid Sunflower Borer.

Sparganothis Fruitworm Moth

White-spotted Leafroller Moth

As mentioned, there are always a few non-moth creatures that come to the white sheet. Here are a few. Some are really small, like this first one, the Citrus Flatid Planthopper.

The occasional Deer Fly, shown next, stopped in, but they don't seem to be interested in biting after dark.

Fire-coloured Beetle
There were several leafhoppers on most nights, and they are all small, with some only about 5 mm in total length. This one doesn't have a common name, but is called Ponana quadralaba.

Northern Flatid Planthopper
This next one is known as Say's Mantidfly. It is considered fairly rare in Ontario. I have had them come to lights at several locations.
Not sure who comes up with names. This next one is the Two-spotted Slope-rumped Beetle.

Two-striped Planthopper
A peculiar looking beetle is this next one, a weevil in the Curculio genus. The very long snout is used to penetrate things like acorns.
