The genus Neoscona
is similar to Caerostris being nocturnal and cryptically coloured. It is
also referred to as the hairy field spider and has a globose (round) abdomen
which overhangs the carapace. The legs are equipped with numerous spines. During
the day this spider takes refuge amongst leaves and in or under bark. Neoscona
species are very variable in colour. This is the spider responsible for the
mysterious orb web found spanning from gutter to balustrade at night only to be
missing next morning. The orb-web is constructed at night, shortly after dark.
once complete the host will position herself head down at the hub (centre) of
the web waiting for prey to fly into the web. Insects are attracted to the
window light and it is quite remarkable how the spider knew to select such an
unnatural but useful site. At the first sign of sunrise, or be fooled at the
rise of a full moon, the spider will remove its web only leaving the bridge
line and a few supporting threads for construction next evening.
Neoscona will be
found resting under the gutter during the day. As the common name implies these
spiders occur in the veld among grasses and bushes. There are 14 species known
from South Africa. It is hoped to update and name the species on photographs at
a later date after reexamining the specimens.
