First record of Megaselia abdita (Schmitz, 1959) (Diptera: Phoridae) infestation in captive tarantulas (Araneae: Theraphosidae

  First record of Megaselia abdita (Schmitz, 1959) (Diptera: Phoridae) infestation in captive tarantulas (Araneae: Theraphosidae Abstract Flies of the genus Megaselia Rondani, 1856 exhibit exceptional ecological flexibility, with certain species acting as facultative parasites. This study presents the first documented cases of Megaselia abdita (Schmitz, 1959) infesting captive tarantulas (Araneae: Theraphosidae, Ceratogyrus darlingi Pocock, 1897 and Psalmopoeus irminia Saager, 1994) in terrarium settings. Our observations demonstrate that M . abdita colonise artificial habitats and exploit spider hosts similarly to Megaselia scalaris . Citation: Szymański, D.M., Szymański, D., Kłonowski, P. (2026).
