Embioptera other food sources. Subsociality is a trade-off for the female, as the energy and time that is exerted into caring for her young is rewarded by giving them a much greater chance of surviving and carrying on her genetic lineage. Some species do share galleries with more than one adult, however most groups consist of one adult female and her offspring. Embiopterans produce a silk thread highly similar to that produced by the much better known silkworm "Bombyx mori". The silk is produced in spherical secretory glands in the tarsi of the embiids enlarged forelimbs, and can be produced by
Müller's larva Müller's larva Müller's larva or Mulleria is a larva of some Polycladida. It has 8-fold symmetry and is somewhat like a ctenophore. Müller’s larva is ciliated and has several paired and unpaired lobes. The cilia on the lobes are longer than cilia on the rest of the body. At the anterior and posterior ends of the larva are tufts of longer cilia (apical and caudal). The apical tuft originates from the apical organ, a sensory structure associated with the central nervous system. It is named after Johannes Peter Müller (1801-1858), a German physiologist who invented the plankton net, and first
