Diggin’ In The Dirt: The Spider Talk
Spiders follow a predictable path. Little
spiders become bigger spiders. Most of the spiders we
see now hatched last spring and live until fall or early
winter. The bigger they get, the more likely they will be
noticed. That is how a lot of very innocent spiders end
up in jars at the Extension office.
Spiders that spend most of their lives outdoors
are by and large beneficial. We have several orb
weavers. They are responsible for the large circular
webs found amongst our flowers and shrubs. One is a
striking black and yellow and another is a more mottled
mix of red, brown, and orange tones. These spiders
capture insects that fly or wander into their webs.
When the prey hits the web, the spider rocks the web
subtly, entangling the hapless insect. The spider dashes
out to inject a dab of a paralyzing agent and the insect
is quickly eaten (more accurately slurped, but that is
another story) or wrapped for a later meal. Often, the
orb weavers will spin their webs near outside lights,
having learned that the lights draw insects. These fairly
large spiders are greatly beneficial and should be left
alone. The wonderful children’s book, Charlotte’s Web
by E. B. White, drew its inspiration from White’s close
observation of orb weavers. If you have only seen the
movie (which I have not and will not), please read the
book. The story telling is magnificent.
Another common spider is a crab spider that
likes to lurk at the center of open flowers. It has some
capacity to adjust its color to blend with the floral color.
This spider does feed on bees but also earwigs and a
number of other insects. Their most common color is
white with some pink highlight lines. Again, it is a
generally beneficial spider despite its occasional bee
meal.
Finally, we have three spiders that like houses,
a lot. This is the Tegenaria family: T. domestica (the
common house spider, T. gigantea (the gigantic house
spider), and T. agrestis (the aggressive house spider,
also known as the hobo spider). All three share some
common patterning and coloration. By far the most
abundant are the common house spider and the gigantic
house spider. The gigantic spider can often be larger
than three inches across if its legs were spread out. It is
a startling spider and is brought into our office a lot this
time of year. Most are concerned it is a hobo spider,
having heard that it causes hard to heal wounds (it can)
and looked up the hobo spider on line. The Tegenarias
are superficially hard to tell apart but if you bring one
in and I happen to be there at that time, I can teach
anyone with halfway good eyesight how to tell if it is
a hobo spider or not. Bottom line is that only the hobo
spider in the Tegenaria group is a potential problem
and they are not very common in comparison to their
relatives.
I also want to say, again for the record, we
do not have brown recluse spiders in Oregon, despite
what you may have heard. There are two population
centers for the two major recluse types: one species is
found in the Los Angeles to San Diego and along the
border region eastward for several hundred miles. The

Wauna FCU Campaign to Raise Funds
for Vernonia’s New School
Wauna Federal Credit Union
will be kicking off a campaign during
the month of October to help raise
money for construction of the new
Vernonia School campus.
According to Pam Weller,
Manager at both the Vernonia and
Clatskanie branches, Wauna FCU
plans to encourage all of their 15,000
members throughout the region to
contribute to the campaign through
a raffle drawing. “For each dollar a
member contributes, they will receive
one chance to win a $500 prize,” said
Weller.
The Wauna FCU campaign
is being run in conjunction with
International Credit Union Day on
October 20th. The 2011 International
Credit Union Day theme highlights
the important economic and social
contributions credit unions make to
their communities worldwide. Credit
unions continually demonstrate and countries around the
their ability to improve the lives of world, and have done so for
individuals, families, communities generations.
