Ants!

PHASE IV-1974-In a geodesic dome in the Arizona desert, two scientists Lesko (Michael Murphy) and Hubbs (Nigel Davenport) investigate the local ant population that seem to be changing their food patterns and building monoliths out of sand. They are actually developing into intelligent and poisonous ants who could be really more than a bother at the next family picnic. The duo get trapped in their lab (along with a local girl named Kendra (Lynne Frederick)) when the insects assert their power. After Hubbs gets bitten he goes crazy and hunts for the queen. He becomes ant bait. Later Kesko goes after the queen himself but fails. He and Kendra seem to become evolved “slaves” for the new invaders. 

This interesting British-American co-production is the only film directed by Saul Bass, the graphic designer known for his credit sequences in films. The exterior scenes were actually filmed in Kenya, while the interiors were done at Pinewood studios in England. Some critics found it too “vague”. It was written by Mayo Simon who'd written the screenplay for MAROONED several years earlier and later created TV's THE MAN FROM ATLANTIS.
