Most of the Mantasphids resembled Earth flies, but much larger. They had six legs, two sets of wings, rounded heads and elongated bodies. Their eyes and abdomens naturally glowed green. The Mantasphid Queen was vastly different in anatomy: She had a bloated abdomen, six large legs and two smaller manipulator limbs, large compound eyes and six large antennae. She towered over humanoids and was capable of speaking. (TV: The Infinite Quest)
