In addition, females have a longer projection that arises from the undersurface of the abdomen called an ovipositor, used to deposit eggs in tree trunks. Siricidae are also called wood wasps. Adults may be confused with sawflies. Females deposit eggs singly, into the wood of host trees. Development is normally completed in 2 years.
Mouthparts are for chewing.
Larvae develop in the trunks of dead and dying trees, including beech, elm, maple, oak and others. Larvae produce a round tunnel in the sapwood and heartwood. For additional information, contact your local Texas extension service agent, or search for other state extension service offices.
