Orb Weavers are a commonly seen spider in gardens and trees. They all seem to have a bulbous abdomen and build circular webs that they sit in. Many are orange, brown, and black. Legs of an Orb Weaver are generally very long, giving length to the overall size of the spider. Males are about 6 mm long, while females can be 10 mm to 20 mm long.
Habitats for Orb Weavers range from tall grasses to the quiet corners inside homes and under protected porches. The web is a masterpiece and the Orb Weaver sits in the middle, head facing downwards, waiting for prey to enter. If the spider is not in the middle of the web, it is usually nearby monitoring the web by way of a "signal" line still attached to the spider. The moment anything gets entangled in the sticky web, the signal line vibrates and the spider comes out to finish its work.
It is reported that Orb Weavers re-spin a new web every night. Their proficiency at nighttime hunting and propensity to eat many insects make them a great tool in lowering mosquito populations. If you find an Orb Weaver near your front door or deck, and it is not in an intimidating area for you or your guests, keep it around and you may notice the mosquito population dwindle in the dusk-to-nighttime hours. Webs set among garden plants help with pest control organically.
