This report describes and illustrates egg types seen among species of three families of Macrolepidoptera-Liparidae, Lasiocampidae and Lacosomidae. For reports on eggs of other families of the Macrolepidoptera see the following publications by the author in The Florida Entomologist: Geometridae (1962); Amatidae, Arctiidae, and Notodontidae (1963); Noctuidae (1964); and Sphingidae, Saturniidae and Citheroniidae (1965). The number of species among the Liparidae, Lasiocampidae, and Lacosomidae is moderate to small when compared with the Noctuidae and Geometridae. McDunnough (1938) records 28 species for the Liparidae, 31 species for the Lasiocampidae, and 3 for the Lacosomidae. Except for the Lacosomidae the females of most species deposit their eggs in irregular or more or less uniform clusters. The eggs of these families were found in the field or obtained from females captured at light traps or at light lures and confined in paper or polyethylene bags. They were handled in the same manner as reported in previous papers by the author in The Florida Entomologist.
