CONDITIONS

TERMITES, or white ants, prefer dead wood and bore inside vine trunks. They have straight antennae (ant antennae are elbowed) and lack a narrow ant-like 'waist' behind their legs. Their bodies are pale and soft except in spring, when they are dark and hard with wings which fall off easily (unlike ant wings).
