Colonies of the common rousette bat (Rousettus amplexicaudatus) from the provinces of Batangas and Rizal, Luzon, Philippines were examined for ectoparasites. Ectoparasites were collected and fixed and stored in 70% ethyl alcohol until further study. Collected specimens consisted of batflies, fleas, mites and tick larvae. These were processed for examination by cleaning in 5% potassium hydroxide solution, washing in distilled water, dehydrating in increasing grades of ethyl alcohol, clearing in oil of cloves and mounting in Canada balsam. The ectoparasites were identified as follows: Two species of batflies, Eucampsipoda sundaicum and Megastrebla parvior belonging to the families Streblidae and Nycteribidae, respectively; a species of flea, Thaumapsylla breviceps of the family Ceratophyllidae, two species of mites, Meristapis lateralis and Ancystropus zelleborii both belonging to the family Spinturnicidae and an undentified tick larvae belonging to the family Ixodidae. Photographs of these species based on the present collection are provided.
