Remember, most arthropods, especially spiders, will bite to defend themselves.
Spiders do not always use venom in a defensive action, but it will cause pain.
Therefore, we suggest that you use caution when observing any spider.
 
Bites and Stings of medically important venomous arthropods
Most phycisians are not trained to properly identify a spider bite.
This results in mistreating a potentially dangerous condition.

This is a common house spider. Some call it the "pillbug spider" because it often leaves the carcasses of its prey in little round "pills" underneath its web. This spider preys upon black widows, so is a good spider, indeed. This spider is a non-hazardous relative to the black widow.

Argiope  aurantia (Golden Garden Spider) female
Other common names: yellow backed spider and black and yellow garden spider. These are fairly common garden spiders and can be from 1/2 to 2" in body length. Arachnologists have not been able to determine why these spiders weave a "stabilimentum" (zig-zag patterns) in their webs. The exact function is unknown.
Argiope  aurantia is pronounced "r-jee-upee  r-anch-ee-a"

Trash Spider
 
 

Cyclosa (Trash Spider)
This spider collects the carcasses of it prey in a vertical line and holds it in its web. The spider is very small and hides amoung the debris. Perhaps being disguised as bird droppings has some advantage.

To catch and preserve spiders for a collection::
  • Wearing gloves is a good idea.
  • Use a clear tall glass to completely cover the spider.
  • Slide a sheet of paper or cardboard under the glass, between the spider and the surface - gently nudging the spider to go on top of the paper.
  • Carefully turn the glass with the cover on it right-side up.
  • Tap the cover enough to cause the spider to fall to the bottom of the container and quickly place a heavier flat object over the top.
  • Place covered container in the refrigerator for at least an hour.
  • Be sure the spider is no longer active and pour a few inches of isopropyl alcohol over the spider. Recover container and wait a minute or two.
  • Document on a small piece of white paper using a lead pencil the place and date found and your name.
  • Transfer the spider and isopropyl alcohol into a smaller container with a tight fitting lid.
  • Place paper with your data in alcohol with the spider.
  • Fill container to the top with isopropyl alcohol.
  • Seal securely.
  • Store in a dark dry place.
To photograph spiders at home: (do this prior to the alcohol bath)
  • A second person is generally necessary to assist.
  • First - refrigerate the spider for 30-60 minutes to slow it down.
  • Set up your photo area using a velvet or other non-reflective surface.
  • Use a coin or pencil tip to give perpective.
  • Use two pionted objects, like long pencils, to reposition the legs.
  • Use supplimental lighting, such as a lamp or flashlight.
  • Photograph the specimen from all angles: top, bottom, front, and side.
  • When spider regains warmth, catch and replace in refrigerator for a few more minutes before your next photo session.          [top of page]
