Garden tent web spider (Cyrtophora cicatrosa)
The garden tent web spider belongs to the family of orb weaver spiders. Although they are in the orb-weaver family, they do not build orb webs. Their tent-like, highly complex non-sticky web is sometimes considered a precursor of the simplified orb web. These webs are aligned horizontally, with a network of supporting threads above them. These spiders often live in colonies. Females have a body length of mostly about 10 millimeters long.
The spider constructs a tent web, about a meter high form the ground. Builds the web in an open environment. Prefers moist and thick surroundings.
Hunting method -
The spider rests at the hub or in the retreat. An airborne insect striking
the upper barrier web either drops onto the horizontal net or remains entangled in the
upper barrier web. The prey produces vibrations in the web upon impact and/or during
struggling, and these are transmitted via web elements to the hub. Some discrimination of prey characteristics on the basis of vibration frequencies
may occur at this stage,
although accurate discrimination of prey type is unlikely. Location of prey
on the web often involves pulling and jerking the net or threads of the upper barrier web
with legs.
Insects are immobilized by biting or by wrapping in silk, or by a combination of the
two methods. If an insect remains caught in the upper barrier web, the spider runs out
under the sheet and shakes it violently until the prey falls on the sheet. Insects that
cannot be dislodged in this manner are attacked and immobilized in the upper barrier
web. The barrier web may be reached by climbing through the open hub, climbing over
the outer edge of the sheet, or by cutting a hole in the sheet and climbing through it.
Insects are rarely attacked in the lower barrier web
