Minnesota Beetles

Order Coleoptera

Coleoptera (beetles) is the order of insects that is characterized by having a biting mouth and two pairs of wings, the outer pair being hardened and meeting in a straight line down the back.

Coleoptera is the largest order in the animal kingdom. There are about 400,000 described species worldwide, about 24,000 species in 131 families in North America north of Mexico. The total number of species, described and undescribed, is probably close to 1,000,000. It is likely that Coleoptera will be split into two or more orders in the future.

Reddish-brown stag beetle


Reddish-brown stag beetle (Lucanus capreolus) is relatively large beetle. It occurs in the United States east of the Great Plains and in adjacent Canadian provinces. It is found around decaying logs and stumps in deciduous forests, parks, and neighborhoods with trees. Larvae feed on decaying wood, adults feed on tree sap. The name “stag beetle” refers to the oversized mandibles on some males that resemble deer antlers. Another common name for this beetle is pinching bug. The mandibles look fierce and are used to fight other males over a female. When confronted, it will rear back threateningly with its mandibles open. However, when handled by humans, it can give no more than a mild pinch.

Adults are reddish-brown and up to 1½ long, not including the mandibles. The antennae have 10 segments, are abruptly bent, and are expanded (clubbed) at the tip. The body appears smooth but is densely covered with very fine punctures. The third and largest segment of each leg is distinctly pale.

Sunflower tortoise beetle


Sunflower tortoise beetle (Physonota helianthi) is a small leaf beetle. It occurs in the United States east of the Great Plains and in adjacent Canadian provinces. It is uncommon throughout its range.

There are three color phases that each adult undergoes. The teneral adult, freshly emerged from the pupal stage, is soft bodied and dingy white or ivory. The intermediate adult is black and white with numerous spots. This phase lasts about three weeks. The mature adult is entirely iridescent green. The upper thoracic plate and the two hardened wing covers each have a semi-transparent covering over the entire surface.

Both larvae and adults feed on the underside of leaves. They occasionally defoliate the plant and can be a major pest. Larvae carry dried fecal matter over their body, presumably as a form of camouflage. The fecal matter is attached to a forked appendage on the last abdominal segment, and is held suspended over the body.

Cocklebur weevil


Cocklebur weevil (Rhodobaenus quinquepunctatus) is a medium-sized snout beetle. It is widespread in the eastern half of the United States. Adults eat the stalks and leaves of cocklebur, ragweed, thistle, ironweed, Joe Pye weed, sunflower, marsh elder, and rosinweed. Larvae bore into the stems and roots of the same species. It is easily controlled and does not occur in numbers high enough to become an agricultural pest.

Snout beetles are identified by their very long snout. Cocklebur weevil is identified by the reddish-orange body; the oval-shaped black spot in the middle of the thorax; and ten black spots on the wing covers that usually merge to some extent with neighboring spots, especially toward the rear.

Rhubarb curculio


Rhubarb curculio (Lixus concavus) is a large, easily identified, true weevil. It is common from New Hampshire, south to North Carolina, and west to Utah. It is uncommon in the upper Midwest, including Minnesota. At up to in length and 3 16 in width, it is one of the largest snout beetles in the United States.

Rhubarb curculio adults are active from mid-May to September. They are found on stalks and leaves of thistles, sunflowers, docks, and rhubarb. They are one of only two weevil species that attack rhubarb. They can be a pest to crops of these plants but they are easily controlled.

Snout beetles are easily identified by their long, flattened or cylindrical snout that is at least as long as the pronotum. Rhubarb curculio is easily identified by the bright yellowish bloom on the head, pronotum, and wing covers.

Colorado potato beetle


Colorado potato beetle (Leptinotarsa decemlineata) is relatively small for a beetle but relatively large for a leaf beetle. Adults are ¼ to 7 16 long and about wide. The body is oval when viewed from above and dome-shaped when viewed from the side. The wing covers are pale yellow with five black lines on each side. The are no similar species in Minnesota.

Prior to European settlement, the Colorado potato beetle was found only in Colorado and neighboring states. The potato was introduced into North America in the 1600s and began to be widely grown in the early 1700s. By 1840 the potato reached the insects home range. By 1859 the insect had switched to the potato as its preferred host, and by 1874 it had spread all the way to the east coast. It is now present across North America, Europe, and Asia.

Colorado potato beetle is a serious crop pest to potato growers. The insect rapidly evolves resistance to chemical pesticides. Many insecticides that once successfully controlled the beetle are no longer effective.

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.
