notes
A larva has been identified by Marcela Skuhravá as an Acodiplosis. Two species are known of this genus, viz. A. inulae, living on Inula species, and A. pulicariae, known from Algeria, Portugal and Spain; that species lives on Pulicaria odora, a plant with a mediterranean distribution and an ecology that widely differs from the one of P. dysenterica.
