Archytas apicifer is a large tachinid fly that belongs to the family Tachinidae. Their name was authored by the German entomologist Johann Friedrich Jaennicke (1867). Presumably named after the Greek classical philosopher and mathematician Archytas. Adult flies are strong fliers and heavily bristled, they have a creamy yellowish thorax, a white head with brown eyes, and a black abdomen. These flies are helpful parasites that attack the Forest tent caterpillar. These common Tachinid flies can be found at flowers and are very common in the summer. Adults are medium to large flies 10–14 mm long. Like all members of the family they hold their wings slightly open to reveal their round abdomen. These flies can be found at flowers throughout much of North and South America. Archytas apicifer rare
