The Noctuidae are the largest family of moths worldwide, with over 21,000 species described. They vary in size from ten millimetres in wingspan to 20 centimetres or more, although with only a few exceptions they are dull moths with grey, brown or black wings and few obvious markings.
Many noctuids have larvae which are serious agricultural pests.
The family is divided up into numerous subfamilies whose characteristics are at present poorly defined. I am grateful to M. Bernard Lalanne-Cassou of INRA, Paris, for his help with identification of many of my Noctuids, where noted. There is no single satisfactory characteristic which defines this group and separates it from all others. I have collected many species from Belize in this huge subfamily so far, but have only identified or partially identified a representative sample of 77 species so far, as listed below. The genus Litoprosopus Litoprosopus sp.
