Did you know that Colorado has an official State Insect? It is the Colorado Hairstreak Butterfly.

Caterpillars are the larval form of the members of this order.

This Web page butterfliesandmoths.org/ can help with identifying butterflies and moths.

Wikipedia has an article discussing the difference between moths and butterflies, at
en.wikipedia.org/wiki/Difference_between_a_butterfly_and_a_moth. The difference is not always clear.


Family Nymphalidae - brush-footed butterflies or four-footed butterflies

A Monarch Butterfly, 27 September 2008 at the Fountain Creek Nature Center. In the fall, these butterflies migrate about 2,500 miles to Mexico to spend the winter hibernating. No other insect can do this. Those from west of the Rockies do the same thing except to southern California.

The second picture is the Monarch caterpillar. The picture was taken on 23 August 2009, at the Fountain Creek Nature Center. It was eating a leaf of a Milkweed plant, the favorite food for Monarchs.

The third picture was taken at the same place, but on 16 July 2010. This one is not quite full grown.

Family Papilionidae -- Swallowtail butterflies.

A Western Tiger Swallowtail butterfly, photographed on 28 June 2009 at the Fountain Creek Nature Center, Fountain Colorado.

But when I look at pictures of the Eastern Tiger Swallowtail butterfly, I find that I can not tell the difference. So, this might be a Papilio glaucus. The Rocky Mountains are usually considered the dividing line, so it could be either one.

An expert on bugguide.net says that along the front range, Pueblo to Denver, the most common is the Two-tailed Swallowtail, which also looks similar. He also says that in Colorado Springs, we could also see the Pale Tiger Swallowtail, so there are four possiblities.

Family Sphingidae --hawk moths, sphinx moths and hornworms. Includes about 1200 species.

This is a White-lined Sphinx Moth (Hyles Lineata) and is also called the Hawk Moth and the Hummingbird Moth.

Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Lepidoptera
Family: Sphingidae
Genus: Hyles
Species: H. lineata


This is the Achemon Sphinx moth, Eumorpha achemon. See www.silkmoths.bizland.com:80/eachemon.htm. I found it still in a cocoon in a flower bed next to my neighbor's Virginia Creeper patch. I kept it until it left the cocoon, and then took this picture (summer 2007). They prefer to dine on grape leaves, or wild grape leaves, but the Virgnia Creeper is close enough. The second picture was taken on 21 July 2008, and the third on 19 July 2009, both in Colorado Springs.

The fourth and fifth pictures were taken on 19 September 2009. It is a large and fat caterpillar, 8 cm in length, same species as the moth above. This one would be the fourth instar. It was found crawling across the floor of our garage. At this stage, they are looking for a place to pupate, usually in the ground or under leaves.

Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Lepidoptera
Family: Sphingidae
Genus: Eumorpha
Species: E. achemon





This one was found on 25 June 2010 in Colorado Springs, Colorado, somewhat hidden on a fence post. It is 2.25" in length. The good folks on www.BugGuide.net identified it for me, as a Ello Sphinx moth. This moth does normally not come as far north as Colorado.

Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Lepidoptera
Family: Sphingidae
Subfamily: Macroglossinae
Genus: Erinnyis
Species: E. ello


This is a Waved Sphinx moth. They are strictly nocturnal, and normally hide as dawn approaches. The small light I left on at my back garage door fooled this one. This one is medium sized, maybe 18 mm. It was found on 20 June 2010.

Family Erebidae: Cutworm moths

This is a common Idia moth. It was found 9 July 2009 in Colorado Springs. It is about 9mm in length.

Class: Insecta - Insects
Order: Lepidoptera - Butterflies and Moths
Family: Erebidae
Subfamily: Herminiinae
Genus: Idia
Specific name: aemula


Family Sesiidae: Clearwing moths

At first, I thought this was a Southern Yellowjacket, Vespula squamosa. But when the experts looked at it, they said that is a female Poplar clearwing borer, one of the clearwing moths. Some call it a Cottonwood crown borer. The larva feeds on Cottonwood and Aspen trees. The scientific name is Sesia tibialis.

This one did not seem to be healthy -- it stayed still even when I got real close with the camera. It moved only when I poked it gently with a twig. But the temperature was 60 degrees at the time, and there had been a rain shower a little earlier, so maybe it was just cold. But moths are usually more tolerant of cameras than Yellowjackets. These pictures were taken on 29 July 2009 in Colorado Springs, Colorado. It was about 2 cm. in length.

This is another good example of how evolution works. A moth which has a genetic mutation that makes it look more like a Yellowjacket will usually live longer than another moth which looks like a moth. Many predators will avoid Yellowjackets since they are likely to sting, whereas a moth doesn't sting. So, it lives longer, and has more offspring with that same mutation. Give it millions of years, with more mutations, and the more it looks like a Yellowjacket, the more descendants it has.

Family Noctuidae: cutworms, dagger moths, noctuid moths, owlet moths.


According to Wikipedia, this family has more than 35,000 known species out of possibly 100,000 total, in more than 4,200 genera.

This moth in the Cucullia genus, a Hooded Owlet, was found on the back wall of my house on 29 June 2009, near a small light which is on 24/7. It is about 2 cm long. It is either a Cucullia umbratica or a Cucullia antipoda. These are the names found on two different photos that look identical to this insect.

This appears to be a moth named the Soybean Looper or Cabbage Looper, also called a Ni moth. This one was 2 cm long. Found 9 November 2008 in Colorado Springs. (This also looks just about like the Gray Looper Moth, next picture. Maybe an identification problem.)

Family: Owlet Moths, Miller Moths (Noctuidae)
Subfamily: Plusiines (Plusiinae)

This caterpillar is an American Dagger Caterpillar. It will turn into the adult form of American Dagger Moth, named for the dagger-like markings on it's wings. It was photographed on 14 September 2009, under a large Maple tree in Colorado Springs, Colorado. It was about 1.5 inches in length.

Species: americana

This is an immature Army Cutworm. The picture was taken on June 4, 2008, next to the young Gladiola plant that it had cut off. The adult of this species is called a Miller Moth.

Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Lepidoptera
Family: Noctuidae
Subfamily: Noctuinae
Tribe: Agrotini
Genus: Euxoa
Species: E. auxiliaris

These are Miller Moths, Euxoa auxiliaris. In early summer, they leave the plains east of Colorado Springs and head for the mountains to escape the heat. They always stop by everyone's house in Colorado Springs for a while. Then, in late summer and early fall, they stop by again on their way back to the plains east of here. Actually, they are the army cutworm, Euxoa auxiliaris.
See www.extension.colostate.edu/4DMG/Pests/millers.htm.

The second picture was taken on 30 April 2009 in Elbert co., CO. I thought that this would be a little too early for them, but I guess not.


This is probably a Yellow-Three Spot, Apamea Helva. It was about 2.3cm long. September 3, 2008 in El Paso County, CO.

Another small unidentified moth, found 8 July 2009 in Colorado Springs. It is about 9mm in length. It is similar to a Yellow-spotted Renia Moth, Renia flavipunctalis.

Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Lepidoptera
Family: Noctuidae

Another small unidentified moth, found 14 July 2009 in Colorado Springs. It is about 9mm in length. It looks a lot like the moth above, but could still be a different species. It is similar to a Renia flavipunctalis, so it is probably a member of the Noctuidae family.

Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Lepidoptera
Family: Noctuidae

This large moth is called the Black Witch. It has many other names in Central America and the Carribean. This one was seen in Colorado Springs, CO on 25 June 2010. It measured 5 1/4" wing tip to wing tip. They reproduce in Mexico, but are strong fliers and are sometimes seen in the Front Range area of Colorado.

Milkweed Tussock Moth Caterpillars, Genus Euchaetes. At first I thought this would be the species E. egle, but that species is found in the Eastern part of the U.S.. Arizona and Texas have a different species, and this one is to be determined. It seems that several species of Euchaetes feed on the Milkweed plant.

About a dozen of these were found on one milkweed plant at the Fountain Creek Nature Center, at Fountain Colorado on 7 September 2008. None were found on other Milkweed plants.

Grass moths, family Crambidae

A moth in the Agriphila genus, species unknown. It was found on 10 June 2009 in Colorado Springs. Length 1.6 cm. there are more than 20 species within this genera. (This could also be in the genus Pediasia -- some of those specimens look the same as some specimens in the Agriphila genus.) Some experts on www.BugGuide.net have placed this picture with their Crambini genus pictures.

Another one, this one found on 12 July 2009. The same size as the above, and found in the same place. There seems to be some minor differences in the markings, so it is probably a different species.
Another one, this one found on 1 October 2009 in Colorado Springs. Small differences in the markings, so it is probably a closely related species.
This is a member of the genus Sod Webworm, a genus that has about 100 species in the United States alone. It was found 12 July 2009 in Colorado Springs. It is about 1.9 cm in length.
