Dear All, Feb 22, 2013
This winter I have seen many spider shelters attached to firewood that
is stored in a covered tier outdoors. I don't recall having seen these
previously. With need to use outdoors wood soon ending I took a few minutes
to look.
The typical shelter, composed of a faintly translucent web fabric is 15
mm long, 9 mm wide and 6 m high. Many don't make it through the winter. On
one xylem surface of split Populus there are 21 shelters or remains of
shelters; 13 of these empty, with a dead exposed spider or missing and 8
intact with spider (perhaps live) inside. Legs are long relative to
cephalothorax dimensions; front leg 11 mm long, cephalothorax 3.5 mm long,
1.5 mm wide. These are somewhat dried dimensions of a dead spider; attracted
to a plastic ruler by static charge.
Does any of this ring a bell ? Will take some photos if/when I have
time.
Yt, Dave Webster, Kentville
