The beginning of wisdom is to call things by their proper name.
This past month, I have tried to find 5 or 10 minutes each day at work to walk around the building breezeways to photograph any moths that were attracted to the lights the previous night. I hope to create a library of images of some of the common species. As I have reported before, I am relatively new to “mothing” and am still struggling to learn some of the more than 2600 reported species in NC. The release of the Peterson Field Guide to the Moths of Southeastern North America last year has made a huge difference in my ability to identify what I find. My copy is already showing signs of wear from the frequent page-flipping. I also refer to the Moths of North Carolina or Bug Guide web sites to confirm an identification.
Now I have another ally in my quest to learn more. It may be a game-changer, in fact. It is the Seek app by iNaturalist. Using the millions of observations on iNaturalist, Seek shows you lists of commonly recorded insects, birds, plants, amphibians, and more in your area. You don’t even need to take a photo, just open the camera and scan whatever you want to know more about. It instantly gives you information, and if it can’t ID it, it may suggest looking at the subject from a different angle. It is usually at least gets you to the family level or beyond even if it doesn’t ID to species. This free app is available for both iOS and Android. I have found it to be particularly useful for moth identification, most likely due to the countless recorded observations of several local moth enthusiasts. In order to get the best possible image, I usually take the photo with my normal camera set-up (100mm macro and twin flash), download the image onto my laptop, and then scan it with my phone and the Seek app for ID help.
I have double-checked many of the early identifications using the other references mentioned and found them to be accurate. A few times, Seek has not been able to provide anything but a family recommendation. But, overall, I have been very impressed with the results thus far.
Here are a few of the highlights from this past month. Note the variety of shapes, colors, and patterns. One thing you can’t tell from these images is the huge range in size – the Common Tan Wave has a wing span of about 20mm while that of the Io moth is about 80mm.
