Grasp of the Zigzag Spider |
Common Name: The black
and yellow argiope is also called banana spider, yellow garden spider,
zipper spider, golden orb weaver and writing spider.
The largest orb weaver in our gardens is the black and yellow argiope (Argiope aurantia). The female is large, the males being much smaller by comparison. Although big enough to deliver a bite, these spiders are not poisonous or aggressive.

Scientific Name: Class Arachnida, Order Araneae, many families
Size: Varies
Identification: Spiders
are not insects; they have no antennae, eight segmented legs instead of
six, as insects do. Many construct webs for capturing prey. Jumping
spiders of the family Salticidae are colorful and leap to capture prey
on the leaves. Wolf spiders of the family Lycosidae run rapidly on the
ground to catch prey at the base of plants. Garden spiders or
orb-weavers of the family Araneidae string vertical webs to trap flying
insects. Funnel-web spiders of the family Agelinidae create funnel webs
and trap leafhoppers primarily. Crab spiders like flowers where they
blend in with the colorful petals waiting to ambush their next meal.
Biology and Life Cycle:
Males are often smaller than females. Not all spiders spin webs. Some
live in tunnels. Most spiders lay eggs in silken sacs, which may be
attached to the web or to twigs or leaves. Some carry the sac with them.
Young are called spiderlings, look like adults, and are often
cannibals.
Habitat: Different
spiders live in many different plants and habitats--beehives, wood
scraps, fencerows, vegetable crops, and ornamental plantings.
Feeding habits: Paralyze with venom and feed on insects and other small animals.
Economic importance:
Spiders are highly beneficial because they feed on many troublesome
insects. Black widows and brown recluses are the only poisonous spiders,
and they are very dangerous ones.
