found: Gibson, M.C. The role of peripodial epithelia in development and regeneration of Drosophila imaginal discs, 2001:p. 10 (imaginal discs are sacs of epithelium and not flat sheets of cells; 2-sided epithelial sacs comprising distinctive peripodial and columnar epithelia; cells of the disc columnar epithelia give rise to the primary adult structures (legs, wings, and eyes), while peripodial epithelia appear to participate in metamorphic events and may also differentiate the parts of the head capsule and the integumentary cuticle of the body wall during metamorphosis)
