Marsh Fritillary

Thirty colonies of the Marsh Fritillary (Euphydryas aurinia) have recently been recorded in Western Bohemia, Czech Republic. The majority of colonies are small, their total area are 1.5 km2. Small size and intensive grazing/mowing were positively associated with observed declines/extinctions, while abandonment threatens the colonies in the longer term. Short distances to nearest colonies buffered against declines. High colony turnover, asynchronous local dynamics pointed and the species’ biotope requirements all point to a dynamic metapopulation structure; patterns of connectivity revealed that there are several metapopulations within the region. Because conserving the species within its extant sites seems unsustainable in the long term, restoration of its habitats is proposed.

Marsh Fritillary

The predatory bug Picromerus bidens is reported as a regular predator of the Marsh Fritillary Euphydryas aurinia from the region of western Bohemia, Czech Republic. Adult bugs attack pre-diapause larvae, either exposed or hidden in protective silken webs, and exhibit efficient behaviour, including returning to previously attacked webs. We observed predation in six out of 28 and eleven out of 21 local populations in 2003 and 2004, respectively. In addition, we observed two attacks by nymphs on handicapped adult butterflies. Predation of Melitaeinae by Heteroptera seems to be a widespread phenomenon, and P. bidens can act as a substantial mortality factor in small colonies of E. aurinia.
