Transcript of Eratigena Agrestsis

Eratigena Agrestsis
AKA
The Hobo Spider

The Hobo makes a funnel like web. The web is not very sticky, therefore instead of a Hobo foraging on what is caught in their web, the funnel web is used more like a "trip line" to stun the prey long enough for the Hobo to attack, kill, and eat their prey. Hobos feed on insects and other spiders.
Reproduction
Hobo spiders mate in late summer. The females stay close to the web. The male will make a series of taps and movements on the web to see if the female is open to mating. The female will lay up to four egg sacs that are filled with up to 100 eggs each. The eggs will hatch in the spring.
It is believed that the Hobo spider was introduced to the United States during the early 1930's via ships coming from Europe docking in the Seattle ports.

Since the 1930's, the Hobo's region has expanded to cover the entire Northwest, as well as, Western Canada.The species continues to expand it's region.
Habitat
Hobos make their nests along foundations and in wood piles. Hobos are not good at climbing and stay relatively close to the ground.

Brief History and Region
Video from YouTube posted by Marc Barry
Hobos are generally found in basements, cellars, and dark areas. The Hobo will come out at night to forage. Although they are not the best at climbing, if you live in a Hobo infested area it is always good to have bedding that does not touch the ground. On occasion, you may even see a Hobo on a wall if the wall is textured. Which shows the species is adapting and evolving.
Side Note
The Hobo Bite
The Hobo is a venomous spider. Where a person has been bitten and whether or not the spider injected venom are very important when dealing with a Hobo bite.
If no venom is injected, the area will turn red, itch, and develop a blister like pustule that will break and scab over. This can take up to two weeks to heal.

The Hobo Spider Bite
This can be the result if a human receives a venomous bite from a hobo spider.
