Blue Jay Barrens has several small areas that are so
inhospitable that very little plant life is able to survive. They are mostly the result of massive erosion
that took place through many decades of poor land management practices. This particular site is primarily rock
covered by a thin layer of silt and clay.
It is excessively wet in the winter and as dry as a baked brick in
summer.
Some plants manage to grow here, but their life is a
struggle. Sometimes odd rarities that
can’t compete elsewhere survive in these bare spots. I enjoy exploring these areas because the
plants are spread out and easy to observe.
What appears to be soil from a distance turns out to be
small gravel. It takes a pretty tough
seedling to anchor itself in this ground.
Insects and other arthropods are the real draw in these
areas. Native solitary bees find the
conditions to be perfect for their underground nests. Many of these species require bare ground as
nest sites.
I visited this site on a cool, cloudy morning, which may
explain why the bees were still in their tunnels. I saw a bee just inside the entrance to about
every tunnel I checked. I imagine they
headed out to forage as soon as the weather warmed.
Little spiders were the most abundant residents this
morning. I think this is the young of
one of the larger Wolf Spiders.
This is a female Thin-legged Wolf Spider, one of the
Pardosa species. These are small, fast
moving spiders that are very difficult to see.
The blue egg sac carried beneath the abdomen is what gave them
away.
That blue egg sac is really something. It gave the spider away every time, sort of
like Rudolph’s nose. It seems that a
spider predator would have no trouble finding these females. Judging by their abundance here, it might not
be so bad if a few do get eaten. When I
crouched down to get some shots, there were a half dozen spiders within camera
range and a lot more not far off. If all
those eggs hatch, that’ll be a lot of baby spiders.
Those are nice shots of the spider.
