An Easy Guide to Insect Identification

After eight consecutive weeks of quarantine quizzes, I’m taking a break. We may or may not see the return of the quizzes, but for this week, I thought I’d offer a free service to readers who may struggle to identify common – or uncommon – insects and spiders.

I post a lot of insect and spider photos on this blog. The fact that I often provide identification of those creatures – at least to family or order – tends to give people the impression that I have extensive entomological knowledge. Nothing could be further from the truth!

This gorgeous ant is Formica incerta. I was able to identify it via a my own very simple method (see below)

As I’ve told many people, I am an insect enthusiast, not an expert. I like to photograph small creatures and then learn about them. However, before I can dig into their fascinating stories, I first need to know who they are. Through years of practice, I have gradually developed and honed a very simple system of identification. Today, for the first time, I am making that system available to the public – at NO CHARGE.

There are, of course, multiple terrific resources available for the identification of invertebrates. Those include various old school field guides, as well as online resources such as iNaturalist and Bugguide. I see my method as complementary to those other resources, if considerably easier to use. It works for any species of insect, spider, or other invertebrate (and, honestly, with vertebrates and plants too). All you need is a reasonably good photo of whatever it is you’re trying to identify. Then, just follow the simple chart below and identify your bug!

You’re welcome. Stay safe, everyone.

Photos of the Week – May 10, 2020

I had a very pleasant hike last night at Gjerloff Prairie, a nearby site owned and managed by Prairie Plains Resource Institute. It was breezy, which made photography challenging, but there was a lot going on. Rain from earlier in the day was moving off to the east, and the cloud remnants were trailing behind the front, breaking up as they followed.

This time of year, flowers are becoming more abundant, but most are small enough they’re not obvious from the distance. Ragwort, pussytoes, blue-eyed grass, violets, prairie dandelion, showy vetchling, and others are all going strong, but the visual aesthetic of the prairie is still driven by last year’s grass, with this year’s grass inserting itself into the picture from beneath. The flowers aren’t hiding, so much as they require proximity to be seen. That provides a nice incentive to hike. Here are a few shots from last night.

Pussytoes (Antennaria neglecta) has finally reached its full height.
Prairie ragwort (Packera plattensis) is abundant, especially where grazing suppressed grass vigor last year.
Showy vetchling (Lathyrus polymorphus) is starting to bloom on the west side of steep hills.
Here’s a closer view of the vetchling.
