Skipper Butterflies

Whenever I do a large post on a particular group of plants or animals, I always seem to start with a disclaimer. Not all of the skippers are illustrated here. I simply haven't seen all the species in Ohio. But in the interest of keeping my posts going, here are a few.

Lepidoptera are the Butterflies & Moths. There are those who like to add AND the Skippers. Like Hymenoptera, the bees, wasps, ants, and Sawflies. Sawflies are a type of wasp, but with fat bodies. Same goes for the Skippers. They are a "type" of butterfly, but have fatter bodies. They are extremely fast fliers, which means they have strong wing muscles. As any collector can tell you, pinning and spreading their wings is quite a challenge. Another difference is many species sit with their upper wings folded, and the hindwings open.

Also look at their antennae. Most don't end in a club. They are swollen, but then form a fine tip. These tips are often curved on many species. There are about 50 different Skippers in Ohio. Over 40 of them are known to breed here. The others are strays, having been recorded only once or twice in the state.

I have collected over 30 of them found in Ohio. My goal now is to photograph them. I could expand this post and illustrate mounted specimens, but as I have been fond of saying, a post that size could go on forever. This is the most difficult family of Butterflies to identify by photos, many of them you need to have 'in hand' to examine fine details. For now I will stick to live shots, but hope to add more on the subject at a later date.

One of our largest and most common species is the Silver-spotted Skipper, Epargyreus clarus. If all you see is the inside of the wings, it could be mistaken for the slightly smaller Golden-banded Skipper.


A quick look at the backside, and the silvery-white patch in the middle of the wing is unmistakable. This species is found statewide.


At the other end of the size spectrum is our smallest species, the Least Skipper, Ancyloxypha numitor. It has a longer body than other skippers. The wings are all orange on the outside, and darker orange inside. These are weak fliers when compared to other members of the family, so look for them in low vegetation near the ground.

The Least Skipper ranges all the way down to Florida, where this shot was taken. It's nectaring on Lippia flowers. In Florida there is a similar looking species called the Skipperling. That species has a broad white band across the back of the hindwing.

Some of the earliest skippers to come out in the spring are the Dusky Wings. These are medium sized skippers that are brown with mottled hindwings. That pretty much describes all of them, as they look quite alike.

One of the things I use to narrow down the species is thegray linebordered by black dots. That makes this either the Dreamy Dusky Wing, Erynnis icelus, or the Sleepy Dusky Wing, Erynnis brizo. Sleepy tends to be found more in dry oak woods, while Dreamy prefers Willows and Poplars and a wetter area. Dreamy usually has much larger gray patches on the forewings than you see here. To me this looks more like a Sleepy, but I have been told this photo is a Dreamy, so I defer to the experts.


Another group of similar looking species include Juvenal's, Horace's, and Mottled Dusky Wings. These  can be recognized by the silvery white spots in the upper wings. The Mottled Dusky Wing, mostly found in southern Ohio, has large black'mottling' on the hindwings.

These are photos of Juvenal's Dusky Wing, Erynnis juvenalis. Notice the two light spots on the hindwing. If these are present on the back of the wing, it's Juvenal's, if absent, it's Horace's Dusky Wing. Also, Juvenal's flies only in the spring months. Horace's can be found all summer. Another thing these skippers have in common, the margin of the wing appears indented along the top. Dusky Wings commonly bask on the ground in open sunlight.

Wild Indigo Dusky Wing, Erynnis baptisiae. I found this species flying among the Blue and White False Indigos (Baptisia) on our prairie. I recognize this species by looking for the several large silvery white cells in the upper part of the forewing, followed by a couple tannish-brown rectangle cells below.

Historically, this species was restricted to fields and open prairies. The flower Crown Vetch, Coronilla varia, has been planted throughout the state, and has broadened the range of this butterfly. Crown Vetch is now the primary host for the caterpillars.


This is the Northern Cloudy Wing, Thorybes pylades. Sometimes mistaken for a Dusky Wing, they lack the mottling of that group. Essentially the wings are a chocolate brown. Look for two rows of 3-4 small white dots coming down from the wing margin. The center of the wing will contain one or two other silvery white spots. The markings are the same on the back. In the similar Southern Cloudy Wing, those little spots are large broad rectangles. Look for this flying along forest edges.


The Little Glassy Wing, Pompeius verna, is one of the smaller, rapid flying skippers. Dark like the Cloudy Wing, it has only one row of small spots coming down from the wing margin. The center spots of the Cloudy Wing are highly separated, in the Glassy Wing they are crowded together. The spots are somewhat translucent.


The backside shows the same spot arrangement, but the hindwing often hides them. The hindwing may or may not show faint spots. Look for the white spot behind the swollen portion of the antennae.

Common Sooty Wing, Pholisora catullus. This butterfly is all black. Look for the S shaped row of white spots. A few pin hole sized spots may also be present. On females, the spots are more obvious. The speckled white head may also aid in identification. These are found state wide in open fields.



Broken-dash Skippers. The top one is the Northern Broken-dash, Wallengrenia egeremet. South of Ohio is the Southern Broken-dash, W. otho. These are orangish-red butterflies when looking from behind. The hindwings have a semi-circular pattern of yellow spots. The forewings are edged in gray.

The inside usually has at least one large light colored rectangular spot. The arrow indicates where the common name comes from. There is a black line near the base of the hindwing. It appears busted in half, like a broken bat. Click on the photo for a closer look. This is a summer species found statewide.


The Sachem Skipper, Atalopedes campestris. Look for white squares randomly placed on the backside. The largest one, out near the edge of the forewing, is transparent. This is especially noticeable on these females. She also has a transparent spot on the inside, right behind a black dash. Both sexes have a black mark inside, but it is not broken like the previous species. In males, the black mark (or stigma) may be square, and half black, half gray. Look for these in open fields, as the  caterpillars are grass feeders.

Here is another species I find difficult to identify when looking at the inside of the wings. It's the Peck's Skipper, Polites peckius. They too have a black dash inside the forewings. It is shaped like a skinny S, but not visible when they hold their wings like this.



I posted several of these because the underside is so distinct. Two semi-circular rows of yellow spots. The inside one narrow, the outside patch broad. It's one of the most common of our small skippers, having been found in every county.


Zabulon Skipper, Poanes zabulon. A very sexually dimorphic species. Male above, female below. The rusty colored female is recognized by the thin white streak at the top of the hindwing.

The male has one big round yellow patch interspersed with dark spots. This yellow patch fills up most of the hindwing.

Here is Sachem, Peck's, and Zabulon side by side. If you are specifically in the field to identify skippers, and it takes too long to sort through pages in a book, simply create your own field guide. Make plates of species you have identified and print them out. It can serve as a quick reference guide.

There is one skipper called the Whirlabout. That's what all of these do. When disturbed they whirl in a very erratic pattern. First they are flying in front of you, and suddenly they disappear.  Don't worry, just turn around, they probably landed six feet behind you.
