Minnesota Moths

 
Order Lepidoptera

Lepidoptera is the order of insects that is characterized by having four large wings; mouthparts adapting for sucking, the proboscis in the form of a long coiled tube; and wings and body completely or mostly covered by scales. The order includes butterflies, skippers, and moths.

There are about 174,250 known species in 126 families worldwide, 12,423 species in 82 families in North America north of Mexico. There are at least 531 Lepidoptera species found in Minnesota.


No Taxonomic Rank: Moths

Differentiating moths and butterflies is complicated because on the tree of evolution (phylogenetically) butterflies are moths. There are 4 suborders and 44 superfamilies of Lepidoptera. Moths comprise three suborders and all but two superfamilies in in the fourth suborder, Glossata.

Moths have feathery or or thread-like antennae without knobs at the end. When at rest, moths hold their wings roof-like over their body, curled around their body, or flat against a support. All other differences have exceptions. Most moths fly at night, are smaller, and have drab wings. Most moths have one or more bristles (frenulum) and scales (retinaculum) that hold their forewings in contact with their hindwings. No butterflies have this feature.

About 93% of Lepidoptera species are moths. According The Lepidopterist’s Society, there are about 127,600 moth species worldwide, about 10,850 species in North America. There may also be between 1,500 and 3,500 undescribed species, mostly micromoths (Microlepidoptera). There are at least 370 moth species found in Minnesota.

Pink underwing
   

Pink underwing (Catocala concumbens) is a medium to large sized, strikingly colored, underwing moth. It is common from northeastern United States, west to the Upper Midwest, and north to Manitoba and Alberta. In Minnesota it is more common in the northern half of the state.

Pink underwing adults are 1¼ to 1½ in length and have a wingspan of 2 to 3. The forewings are a nondescript, mottled gray and tan with a pale, kidney-shaped spot and two thin, jagged, black lines. The hindings are pink two black bands and a wide white fringe. They are active at night. When at rest the wings are folded roof-like over the body. When approached or disturbed they spread their forewings revealing the startling color of the hindwings, possibly to scare off or give it time to escape a predator.

There are 39 underwing moth species found in Minnesota, and most are similar in appearance. Pink underwing is distinguished by the pale colors and paler reniform spot on the forewings; and by the pink hindwings with a wide, straight, uninterrupted, white fringe.

Arcigera flower moth
   

Arcigera flower moth (Schinia arcigera) is common and widespread across North America from the east coast to the Rocky Mountains. In Minnesota, it is found from late July to mid-September in fields with asters.

It is active at night and is attracted to light, but can be also found taking nectar on flowers during the day.

This is a small owlet moth. The adult is about ½ long and has a wingspan of to 1. It is distinguished from similar moths by dark brown and pale brown coloration, and by a white, smoothly curved, broadly S-shaped postmedial line.

Toothed somberwing
   

Toothed somberwing (Euclidia cuspidea) is common and widespread across North America from the east coast to the Rocky Mountains. In Minnesota, it is found from mid-May to early July in meadows and in woodland edges and openings with long grass.

It is active both day and night. When flushed from vegetation it flies rapidly for about 20 yards then drops to the ground. It rests with the wings held flat and the hindwings usually concealed. It is attracted to light.

This is a stout, medium-sized moth. The adult is about long and has a wingspan of 1 to 17 16. It is distinguished from similar moths by dark brown triangular spots on the forewing of the adult, and by the presence of reduced leg-like structures on the fourth abdominal segment of the caterpillar.

Robin’s carpenterworm, A Very Large Micromoth
   

Micromoth is an artificial grouping having no taxonomic equivalent. The name suggests that these are small moths, and indeed most have a wingspans of less than ¾. However, micromoths are not distinguished by size but by wing venation and the female reproductive tract.

Carpenterworms are wood-boring micromoths. The caterpillars feed by boring into the cambium layer of a tree. This creates galleries and tunnels under the outer bark that decrease the value of the wood and can sometimes kill the tree. Wood has little nutritional value. As a result, the caterpillars take 3 or 4 years to complete their life cycle. They pupate in the spring of their final year and emerge as adults between May and July.

Robin’s carpenterworm (Prionoxystus robiniae) is a medium-sized moth but a very large micromoth. Adults are 11 16 to 1¾ long with a wingspan of 17 16 to 3. They are similar in size and appearance to sphinx moths and are often misidentified as such. They are distinguished by their large size, heavy body, abdomen that extends well beyond the hind wings, light gray wings with a net-like overlay of thin dark lines, accessory cell and 2 complete anal veins on the forewing, 3 anal veins on the hindwing, and yellowish-orange patch on the hindwing of the male.

Hitched arches
   

Hitched arches (Melanchra adjuncta) is a stout, medium-sized, night-flying, owlet moth. It is common in moist woods along river and stream banks, in woodland edges and openings, and in old fields. It is also often found in large gardens.

When at rest the forewings are held roof-like over the body. The forewings are dark gray mottled with black, greenish-brown and white. They have a white patch near the base (closest to the head), a small round white spot, a large white kidney-shaped spot, and a gray fringe. The hindwings are light grayish-brown but are not usually visible.

The caterpillar is light green or light brown with dark semicircular patches on the back (dorsum) and a conspicuous hump near the end of the abdomen.

Capitalization of Common Names

Insect scientific names are governed by the International Commission on Zoological Nomenclature (ICZN). Vernacular (common) names are not. In an attempt to “assure the uniformity of (common) names of common insects” the Entomological Society of America (ESA) published Common Names of Insects and Related Organisms. ESA has no rule or guideline that addresses capitalization of common names. However, the database of common names published by ESA does not capitalize common names. National Center for Biotechnology Information (NCBI) also uses uncapitalized common names. Most other sources, including ITIS, BAMONA, Odonata Central, and the Peterson Field Guides, capitalize common insect names. MinnesotaSeasons.com will adhere to the convention followed by ESA and NCBI.
