| behavior |
Spider sits in center hub at night, rests with legs folded in front to a point on a leaf during the day, sometimes out in the open. Egg sacs laid in a open leaf, can be guarded by female. Populations may be dense. Can be found by sweep netting vegetation. Females startled by bright lights can deconstruct their web in less than a minute by cutting the support lines and eating the web as they roll it up. |
