G. bicolor can be found under bark year-round. Females produce purse-shaped mud cells under leaves. Eggs are laid here. They are fond of moist areas, which can include woodlands, meadows, and backyards. They are usually encountered either dead or under leaf litter or a rock or log. In the wild, they can live about 1-2 years. They are most active from February-November. They eat insects as larvae and adults, and are mainly hunted by
birds. ==References==
