BURROWING WOLF SPIDERS:
The Stay-at-Home Predators
Student Data Sheet
- Carefully search the flagged area for burrows made by a scrub burrowing wolf spider. If
you find one, stick a toothpick into the sand about 2 cm from the hole to mark the burrow.
Look for more burrows nearby and mark them, too.
- Being as gentle as possible, measure how wide the burrow hole is.
- Observe the area right around the burrow hole. What does it look like?
(Circle the right answer.)
Does the area have:
|
| a. open sand |
yes |
no |
| b. lots of leaf litter (dead leaves)? |
yes |
no |
| c. many small plants and grasses? |
yes |
no |
| d. a tall tree less than a meter away? |
yes |
no |
- What does the burrow entrance look like?
| a. Does the hole have any sand piled up around it? |
yes |
no |
| b. Do you see a turret (raised collar) of leaves around it? |
yes |
no |
What do you think spiders do with the sand they dig from the burrow? Why?
- With a pine needle or long grass stem, carefully tickle the edges of the burrow opening.
Watch closely for the spider, who might come up to the surface to see the "bug"!
| Did you see the spider? |
yes |
