The Acari collection was started in the early 1950's and is now one of the largest in North America with more than 116,700 microscope slides and over 1,000 vials. The Acari types in the Museum of Entomology (FSCA) number more than 1,338 specimens representing 413 nominal taxa in 18 families and 82 genera. This type material includes 158 holotypes, 1 neotype, 42 allotypes, and 326 paratypes. The family with the largest holdings is the Phytoseiidae with 132 holotypes, 42 allotypes and 223 paratypes. In addition to the slide collection, we maintain a collection of Berlese residues from Florida and other areas.

The Acari slide collection is strong in plant-associated mites, especially Tetranychidae, Tenuipalpidae, Tarsonemidae, Tydeidae and Phytoseiidae. Along with the Phytoseiidae, the FSCA has one of the best terrestrial Parasitengona (excluding chiggers) collections in the world. Collections from H.L. Cromroy, E.A. Cross, H.A. Denmark, K.E. Hyland, M.H. Muma, N. Wilson, J.P Woodring, and C.E. Yunker make up part of the Acari collection.

The National Musuem of Natural History, Smithsonian Institution (NMNH) Phytoseiidae type collection is on long term loan to the FSCA. The FSCA curates and processes loans for this important collection. The collection consists of 193 holotypes, 30 allotypes, 2 cotypes, 1 neotype and a syntype representing 253 species in 42 genera.
