Minnesota Spiders
Order Araneae |
||
Araneae (spiders) is the order of arachnids that is characterized by breathing air, having eight legs, and having chelicerae (mouth parts) with fangs that inject venom. There are 43,678 known species in 3,705 genera in 109 families worldwide. There are about 3,400 species in North America and at least 466 species in Minnesota. |

Orbweavers (Family Araneidae) |
||||
Araneidae is a large family of typical spiders known as orbweavers. It is the third largest family of spiders. There are 3,067 currently recognized orbweaver species in 177 genera worldwide, 180 species in North America north of Mexico, and at least 44 species in 16 genera in Minnesota. Orbweavers are found in woodlands, fields, and caves; on grasses, shrubs, and trees; and on buildings and fences. They are best known for the circular webs, called orbs, that they build. The webs consist of a framework of non-sticky threads (spokes) extending from the edge to the middle, and concentric circles of sticky threads winding to the center. Orbweavers are very diverse in size, shape, and color. They have eight small eyes in two rows. The lateral eyes are usually well separated from the median eyes. The median ocular area (MOA), the area defined by the middle four eyes, is in the shape of a trapezoid. The front part of the body (carapace) is smaller than the rear part (abdomen). The abdomen is large, rounded, and marked with lines, spots, or zig-zag patterns. The legs are short and spiny. The first and second pairs of legs project forward, the third and fourth pairs project backward. There are three claws at the end of each leg, though these are not visible without magnification. Females are much larger than males. |

Fishing spiders (Dolomedes spp.) |
||||
Dolomedes is a large species of nursery web spiders known as fishing spiders, raft spiders, dock spiders or wharf spiders. There are more than 100 currently recognized species worldwide, 8 species in North America north of Mexico. Four species have been recorded in Minnesota. Fishing spiders have a worldwide distribution, occurring on every continent except Antarctica. They are usually found near permanent bodies of water, or on floating vegetation in a body of water. Some are found in grassy meadows. One, dark fishing spider, wanders well away from water. One, white-banded fishing spider, lives in trees. The remainder are semiaquatic, spending part of their time in or on water. Some fishing spiders sit quietly at the edge of a lake or pond or on floating vegetation. They rest their front three pairs of legs on the water surface to detect ripples or vibrations of prey. Others stalk prey on land. They eat mostly aquatic insects but also small fish. None hunt from webs, but all make nursery webs for their young. All fishing spiders are covered with water repelling (hydrophobic) hairs. They are able to run across the surface of the water and even to “climb” under the surface to subdue prey. When they submerge, air is trapped on the underside of their abdomen, and they are able to breath underwater. |

Common house spider |
||||
Common house spider (Parasteatoda tepidariorum) is the most common house spider in the eastern United States. It has a cosmopolitan distribution, occurring on every continent except Antarctica. In the United States it is common east of the Great Plains and west of the Rocky Mountains, uncommon between. Common house spider is found in and around human dwellings, sheds, barns, and privies, in stables, under highway bridges, and in culverts. It appears year-round when indoors, but it cannot survive northern winters outdoors. Its web is often built in upper angles of rooms and in corners of window frames and doorways. It hunts at night, hanging upside-down in the middle of the web. During the day it retreats into a corner or a crack. Common house spider is a medium-sized colorful comb-footed spider. The front part of the body is short, flat, highest in the middle, and yellowish-brown. The back part of the body is gray with white and dark markings. There is a dark horizontal line just before the highest point, white chevrons before the line, a white spot just behind the highest point, and dark chevrons behind the spot. On lighter individuals the markings are indistinct. On the male the abdomen is more slender. The legs are yellow with dark bands on the female, orangish on the male. |

Orchard orbweaver |
||||
Orchard orbweaver (Leucauge venusta) is a sedentary, small, brilliantly colored, long-jawed orb weaver. It is one of the most common spiders in the eastern United States, but is less common in Minnesota, where it reaches the western extent of its range. It is found in forests, dense woodlands, woodland edges, shrubby meadows, gardens, and orchards. The species name venusta is Latin for “beautiful” and it is easy to see why it was given to this spider. The abdomen is silvery-white with four pairs of dark stripes, a yellow stripe on each side, and often a pair of bright coppery-red spots toward the rear. Charles Darwin collected this species in 1832 on his voyage of the Beagle. He named it Leucauge argyrobapta. Both names are from the Greek, Leucauge meaning “with a bright gleam,” and argyrobapta meaning “dipped in silver.” The specimen was lost after Darwin’s voyage back to London. In 1973, as party of an experiment to study web building in zero gravity, two orchard weaver spiders were brought to the U.S. space station Skylab 3. After some time to adjust to weightlessness, the spiders constructed complete webs that were not much different than those constructed on earth. |

Brilliant jumping spider |
||||
Brilliant jumping spider (Phidippus clarus) occurs across North America from coast to coast. It is very common in Minnesota. A study in 1997 surveyed jumping spiders in 30 locations around Minnesota. The author collected 572 jumping spiders representing 15 species. Brilliant jumping spider was by far the most common, with 299 specimens (52%) collected. Brilliant jumping spider is found from July to September in moderately moist fields on grasses and perennial plants. It is a small to medium-sized spider (order Araneae) but a relatively large jumping spider (family Salticidae). Adults are mostly black with four pairs of white spots and two red stripes on the abdomen. The female is a paragon of parental perseverance. In the fall she creates a large white egg sac at the top of a tall grass or herbaceous plant and drops eggs into the sac. She prevents the eggs from drying out by repeatedly adding silk to cover the egg mass. She stays with the egg sac until the young disperse in about a month. During this time she does not feed and usually dies from starvation a few days later. |

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.
