Of all our little neighbors of the fields there are none that are more
universally shunned and feared than spiders, and few that deserve it
less. There is a wide-spread belief that spiders are dangerous, that
they are liable to bite, and that their bites are very venomous. Now
this may be true of certain large species that live in hot countries;
but the spiders of the Northern United States are practically harmless.
It is true, spiders bite and inject venom sufficient to kill a fly into
the wound made by their jaws. But they are exceedingly shy creatures,
fearing man more than they are to be feared. If an observer will refrain
from picking up a spider there is not the slightest danger of being
bitten by one; and excepting a single uncommon species no spider is
known in this part of the country whose bite would seriously affect a
human being.
On the other hand, spiders do much to keep in check various insect
pests, and hence must be regarded as our friends. It is, however, from a
different point of view that we wish to look upon them at this time. It
is as illustrations of remarkable development of instinctive powers, and
of wonderful correlation of structure and habit, that we would have the
reader study these creatures. The teacher of nature-study can find no
more available or more fertile field from which to take subjects for
interesting children in the world about us. Let us then put aside our
fears and go into the fields and see whether we can learn something of
the ways of these spinners.
THE FUNNEL-WEB WEAVERS.
Often on summer mornings the grass of the roadsides and fields is seen
to be carpeted with little sheets of glistening silk, the webs of the
grass-spider. None were observed the day before; and we wonder at the
sudden appearance of this host of weavers. Later in the day the webs
have vanished! Have the weavers rolled them up and carried them off? We
remember that there was an especially fine one near the end of the
veranda steps; we examine the place carefully and find that it is still
there, but not so conspicuous as it was. The warm sun has dissipated the
dew which rendered visible to our dull eyes the tapestry of the fields.
Now that our eyes are opened we can find the webs everywhere and are
impressed with a suspicion that perhaps ordinarily we see very little of
what is around us.
We examine one of the webs carefully and find that it is a closely woven
sheet made of threads running in all directions; that it is attached to
spears of grass, and supported by numerous guy lines, and that from one
side a funnel-like tube extends downwards. If, while we are watching, an
insect alights on the sheet, there darts from the tunnel, where she was
concealed, the owner of the web, a dark-colored spider; and the insect
must be agile if it escapes.
