In New Leaf
"Tiger beetles are known for their aggressive predatory habits and fast running speed. Their bodies are rather colorful and reflect the sunshine, giving them a shimmery appearance. Tiger-beetle larvae live in cylindrical burrows and capture insects that wander past with their mandibles."
