  • Author(s): Hoddle, Mark; Morgan, David; Triapitsyn, Serguei;
  • Abstract: Information from identification receipt vouchers prepared by the Florida State Collection of Arthropods, Bureau of Entomology, Florida Department of Agriculture and Consumer Services in Gainesville over the period 1958-2001 for Homalodisca coagulata were analyzed for information on host plants and distribution in Florida. Homalodisca coagulata was recorded from at least 72 plant species in 37 families and greater numbers of H. coagulata were sent in for identification from northern Florida even though there were no significant difference in specimen submission frequencies from north, central, and south Florida.
