Thiamethoxam is a neonicotinoid, IRAC Group 4A. It is systemic, moves inside the plant, and works mainly on sucking pests with residual effect. Lambda cyhalothrin is a pyrethroid, IRAC Group 3A. It stays on the surface, kills fast on contact, and covers chewing pests as well. Together they cover what neither does alone.
