Mantasphid

The Mantasphids were a species of sapient, phosphorescent insects.

Biology
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 manipulatory limbs, large compound eyes and six large antennae. She towered over humanoids and was capable of speaking. (DW: The Infinite Quest)

History
During the 40th century, the Mantasphids had invaded Myarr, needing the dung produced by the livestock. There was an all-out war on the planet, with the Mantasphids building huge hives in the forests.

On Volag-Noc, Ulysees Meregrass learned of the conflict from a Mantasphid who was incarcerated there. He decided to take advantage of it and made a deal to ship weapons to the Mantasphids. While making a delivery, he picked up the Doctor and Martha Jones and brought them to the Mantasphid queen. At the same time, the Humans believed that the war was too far gone and were planning to destroy the Mantasphid city and everything else in a 100 mile radius. Though the Mantasphids intended to fight back, they also refused to pay Meregrass and he refused to give them the weaponry. As there was no other option, the Mantasphids agreed to surrender. The Doctor then claimed to have controlled the Mantasphids, removing them of all blame. (The Infinite Quest)
