the anthers are destroyed ….
…. but the ovary is not affected (however, note the larva of Contarinia steini below left)
the content of the anthers is transformed into a brown vinaceous mass of spores
Caryophyllaceae, narrowly monophagous
because the larva leaves the ovary intact, the negative impact on the reproductive capacity of the flower is very limited. The real damage is caused by the Contarinia.
