Immatures are found in water, usually in flowing water. Larvae are scavengers, herbivores or predaceous. They can spin silk and use it to form nets to strain material from the water to eat or to form cases in which to hide. The type of case or use of silk for a web depends on the species. Pupal cases are often attached to objects.
Adults generally fly quickly from the water.
Mating takes place on the ground or vegetation. Adults are commonly found near lights at night or on foliage near water. For additional information, contact your local Texas extension service agent, or search for other state extension service offices.
