Phanacis hypochoeridis - Phanacis hypochoeridis

Description

The larva of the cynipid wasp Phanacis hypochoeridis causes galls to form in Cat's-ear (Hypochaeris radicata). This takes the form of an elongated swelling, usually in the main stem of the plant, but sometimes in the flower stalk or petiole, succulent at first, later hard often wrinkled inside – up to 50 chambers, each with a yellowish-white larva. The gall is seen more often than the adult wasp.
