Minnesota Harvestmen

Order Opiliones

Opiliones (harvestmen) is the order of arachnids that is characterized by having a body that appears to be a single segment and having generally very long legs.

There are 6,491 known species worldwide, though the actual number of living species is thought to be close to 10,000.

Common Names
The common name “daddy long legs” is commonly used for all harvestmen. However, that name is also often applied to crane flies and cellar spiders. The common names “brown daddy long legs” and “eastern daddy long legs” have sometimes been used to describe single species or an entire genus. However, their use has not been consistent and the names are not widely accepted. In short, harvestmen species do not have individual common names. Each species can be referred to by the common name of a higher taxonomic classification. In this case, the order Opiones has the common name “harvestman”, and that common name will be applied to all species listed here.
Commonly Seen

Virtually all of the harvestmen seen are “wanderers” of the suborder Eupnoi. The most widespread species of harvestman in the world is Phalangium opilio. It is the most common species found in disturbed habitats in Europe, Asia, and North America. In the eastern United States, the genus Leiobunum is both abundant and conspicuous. Identification of Leiobunum harvestmen to the species level is to a large part based on microscopic features. Species determination is difficult or impossible either in the field or by looking at photographs.

Capitalization of Common Names

The 1997 version of Common Names of Insects and Related Organisms, published by the Entomological Society of America (ESA), contains only 9 spider species. Two of those are placed in the wrong family and four are unrecognized common names. The inadequate coverage of arachnids by the ICZN spurred the American Arachnological Society (AAS) to develop their own list, Common Names of Arachnids. While the ESA has no rule or guideline that addresses capitalization of common names, the AAS does. Capital letters should not be used unless 1) the name begins a sentence, then the first letter of the name should be capitalized; or 2) the common name begins with a proper name, and that proper name begins with a capital letter (place name or person’s last name). MinnesotaSeasons.com will adhere to the convention adopted by AAS.
