For me and many others, butterflies evoke a great sense of wonder. Their appearance and habits make them fascinating creatures both to study and photograph. In Europe there are just over 450 species of butterfly to be found; some are widespread and common whilst others are found only on a single mountain or island. Ireland has a relatively cool and damp climate and consequently only supports around 35 species. Below is a list of European species that I have seen on my travels, with the Irish species marked with an asterisk. Each page has at least one photo of the relevant butterfly species as well as a picture of its habitat. In some cases I have either bred or come across various pre-adult stages of some species and photos of these have also been included. Within each species page, there is information regarding the larval foodplants and nectar sources used by each species. Because many continental European butterflies use plants for which there is no English name, I have included the scientific species names for all plants mentioned in the following pages. 

Papilionidae (Swallowtails, Apollos and Festoons):
Swallowtails are large, predominantly white butterflies with characteristic hindwing tails. Apollos are also large, pale species who are graceful fliers that often dwell in higher altitudes whilst the festoons are strikingly marked spring butterflies. Represented by around a dozen species in Europe.

Scarce Swallowtail (Iphiclides podalirius)
Apollo (Parnassius apollo)
Small Apollo (Parnassius phoebus)

Pieridae (Whites):
Medium or large butterflies which are predominantly white or yellow in colour. The clouded yellows are strong fliers and all use members of the pea family as larval hostplants. The orange-tips are spring butterflies, usually with some amount of orange on their forewings. The brimstones are medium-sized yellow butterflies with leaf-shaped wings which use various buckthorns as larval foodplants whilst the whites are the most numerous and widespread with most favouring members of the Brassicae family as hostplants. Around 50 species occur in Europe.

Lycaenidae (Hairstreaks, Coppers and Blues):
Small, often brightly coloured butterflies represented by over 100 different species in Europe. The hairstreaks are mostly arboreal species with hindwing tails and a preference for shrubs and trees as hostplants. Coppers are often bright shades of orange and almost all of them use docks, sorrels and bistorts as foodplants. The blues are a varied group, but males of most species have a variable amount of blue colouration their upperwings. Foodplants are very often members of the mint and pea families. All species in this family have small, woodlouse-shaped larvae and many have a symbiotic relationship with ants.

Danaidae (Milkweed Butterflies):
In Europe this family is represented by 2 species, both of which are very large, predominantly orange butterflies who  lay their eggs on various species of milkweed. Both are highly migratory and often set up temporary breeding colonies in southern Europe.

Monarch (Danaus plexippus)

Nymphalidae (Fritillaries and Vanessids):
Sometimes called the Brush-foot butterflies, characterised by their possession of 4 walking legs and 2 brush-like appendages. Fritillaries are predominantly orange butterflies with many members feeding on violets, plantains and cow-wheats.  Vanessids are very often large and impressive butterflies with most species using nettles or deciduous trees as hostplants.  There are around 70 species in Europe.
