Planting for Butterflies
Many of the UK's native wildlife species are under some form of threat, whether by competition from non-native species, loss of habitat, changing weather patterns, changing land use and so forth. Our moths and butterflies are no different and we can all do our "bit" by considering what species are present in our own region and introducing plants into our gardens that will provide food and habitat for the adult insects and also their larvae.
https://butterfly-conservation.org/ have prepared [this list] of forage plants for butterfly larvae which you may wish to consider when planning your planting in your garden. Their website is packed with really accessible information for novices and experts alike and is well worth having a good rummage around.
