fisherwr2 > A hornworm that has been parasitized by a wasp, which laid eggs in the host. The eggs hatch into wormlike larvae that feed internally on the host tissues. When they finish feeding, they chew a hole in the integument of the host and crawl outside to construct a cocoon. Some worms (center and lower right) were caught by the camera in the process of crawling through the integument, while others that crawled out earlier have already started constructing cocoons in which to pupate. The cocoons will remain on the outside of the host until the adult wasps emerge (see other photos in this gallery)
fisherwr2 > A paper wasp, Polistes exclamans (Hymenoptera: Vespidae) constructing a nest. This queen uses masticated wood fibers and salivary secretions to make the nest. Note the egg already deposited in the upper cell. The cells remain open for the duration of the larval stage so the queen can feed the larvae. Prior to pupation the queen covers the openings. The offspring from this queen will be sterile and help tend additional larvae produced by the queen. This image was featured on the cover of the winter 2008 edition of American Entomologist published by the Entomological Society of America
