Thelarvae are fed continually by the adults, which are common and generally distributed. Anopllus tropicus Fab, July £3. One specimen from Pycnanthemum at the margin of theI-Iatan^as Lake forest. Plart found it common in many other partsof the sand regions. He records ten species of iinoplius. Thefamaily, Ceropalidae, includes digging species v/hich prey uponinsects and spiders.
