Drosophila hydei (mosca casera) is a species of Diptera, or the order of flies, in the family Drosophilidae.

[2] Drosophila hydei are commonly found on compost piles worldwide, and can be rudimentarily identified by eye owing to their large size and variegated pigment pattern on the thorax.

[5] The Class II "Minos" transposon was identified as a repetitive element in the genome of Drosophila hydei.

Minos transgenic tools derived from the element in Drosophila hydei have been used in an extremely wide variety of invertebrate and arthropod genomes to disrupt genes for study.

[9] The DNA required to make this sperm has large introns, genetic material that is removed before the rest is translated into proteins.
