A case of human intestinal myiasis due to Leptocera venalicia is reported. This species apparently has not been previously reported in connection with human myiasis. Larvae and pupae appeared in various stool specimens over a period of five months. Except for occasional episodes of gastric distress and abdominal cramps, the patient was essentially asymptomatic. The patient probably ingested eggs or larvae with contaminated meat or cheese. The heavy fly population at the patient's home was conducive to myiasis.
