THE PARASITISM OF BLACK FLIES (DIPTERA, SIMULIIDAE) BY LARVAL WATER MITES MAINLY OF THE GENUS SPERCHON
Larval sperchonid hydracarina, possibly Sperchon jasperensis Marshall, parasitized adult simuliids in Canada. All stages of the water mites were found during the summer. Larval mites gained access to adult black flies as they emerged. Parasitism occurred from spring until fall, reaching a peak in Ju...
