Lacewings are generalist widespread predators with potential for use in biological control programs. The objective of this study was to describe the anatomy and histology of the alimentary canal and the ovarioles of Caraeochrysa cubana (Hagen) (Neuroptera Chrysopidae) adults. In the foregut the crop, proventriculus stomodeal valve are well developed. In the midgut the digestive cells, had a well-developed striated border, evident peritrophic matrix. Externally the midgut wall showed a layer of circular muscle followed by longitudinal ones. The mid-hindgut transition was characterized by the opening of numerous Malpighian tubules that were thin and formed by a single layer of cuboidal cells with small nucleus. The final portion of the alimentary canal of C. cubana was formed by a sac-like rectum that showed the wall with a layer of flattened cells and six rectal pads characterized by an inner layer of columnar cells and an external one of flattened cells, separated by a narrow space. The ovaries were of meroistic polytrophic type, like other species of the order Neuroptera.
