does anyone know if its possible to introduce marsh fritillary butterflies onto your land - eg, through larvae (caterpillars)? I've got a large area of land with good plants/flowers etc and wanted to try to increase the amount of butterflies currently there. I confess that I know little about butterflies but i've become obsessed with wildlife since moving to the country. recently had nesting woodpeckers and owls, baby rabbits etc. any advice greatly appreciated thanks
