ers are often found where they have been hanging out. =A0A spider will shed=
 the exoskeleton - I think it is 9 times - during its growth. =A0The exuvia=

 been shed. =A0They tend to bleach out after a few days. =A0In my pbase gal=

beneath a board soon after it had shed its exoskeleton. =A0The interesting =
thing was how the spider ran back to the exuviae when it realized that it w=
as being observed. =A0It may have felt safer there. =A0As you will note fro=
m the photo, this spider was quite a bright almost-orange colour. =A0The no=
rmal colour would be a dull brown. =A0As is the case with many creatures th=
at shed their skins, a freshly shed spider tends to look a bit brighter tha=

ire on the under-body carrier, I noticed weirdly stretchy spider webbing th=

the spider inside the trailer hitch socket, behind a plastic cover. =A0The =
large female was inside the socket with several her own exuviae and the dri=
