SPIDERS:
An Organism for Teaching Biology
Teacher Overview - Pt. B
Collecting Spiders.
Students will be assigned to bring in at least
one live spider in some kind of container, preferably a clear
container, in order to easily observe the spider. Spiders can do
very well in a small vial but larger containers, such as an empty
jar, provide more space for the spider to go about its business--an
important consideration for behavioral studies. Examples of suitable
containers should be shown to the class.
Caution.
Two spiders in North America including Arizona are dangerous:
the brown recluse and the black widow. The brown recluse is small,
has a violin marking on its back, and hides. The black widow adult
female is large and usually black, but others may be small and
brownish and may have red or yellow hour glass markings on the
dorsal side of the abdomen. All have a red or yellow hour glass
on the under (ventral) side. These spiders should not be handled
directly.
Other spiders are not so dangerous, are reluctant
to bite, and may be handled. However, they could be dangerous
to allergic individuals. Their bite is no worse that a bee sting
or mosquito bite. Still, care should be taken. Use a twig or piece
of paper to transfer the spider to the container or capture the
spider directly in the container if possible. If a jar is brought
down over a spider, a piece of paper can be slid between the jar
opening and the substrate so that the jar can be turned upright
and then capped without loosing the spider. It is convenient to
have a small hole (approximately 1/4" diameter) made in the
container to add prey items. The hole can be corked or fitted
with sponge to prevent live contents from escaping.
Where to look: on the sidewalk, in trees, on rocks, on
the wall around the porch light, in the house, on flowers, in
bushes, etc. Try taking a tree branch and pulling it down hard,
shaking it on a white piece of paper supported by your binder
to see what falls out of it.
Also look for and capture insects to feed the
spider. Flies will be provided in the classroom, (fruit flies
and house flies). Show students how to use pooters. Provide materials
for students to make their own pooter. Two sizes of plastic tubing
and old nylon stockings are the materials needed.
Need directions?
See "Special Spiders Tools"
for tips on making spider rakes and pooters.
Have students keep collecting records. On
a small piece of paper, they should write down the following:
- where they found the spider
- describe the area
- indicate if it was in a web, on the ground, in a tree, etc.
- include the date it was collected
- include the name of the person who collected it
- write collected by and student's name.
Remind students to keep the collecting record in
the container with the spider. One week should be ample time for
students to find a suitable container and collect a spider.
