Meadow Brown Butterfly - Maniola jurtina.
Similar species are the Gatekeeper (which prefers to rest with its wings open) and the Small Heath (which is smaller) and the dusky Meadow Brown (Hyponephele lycaon).
A variable number of smaller eyespots are usually found on the hindwing undersides. These may number up to twelve per butterfly, with up to six on each wing, but sometimes none. The factors that govern polymorphism in this trait are not resolved, although a number of theories have been proposed . The evolutionary significance of the upperwing eyespots is more obvious: The more active males have a markedly more cryptic upperside pattern, whereas the females have more opportunity to present their eyespots in a sudden display of colors and patterns that presumably startle predators so the butterfly has a better chance of escaping. Some specimens are bi-pupilled.
Recorded larval food plants include rough meadow grass (Poa trivialis), smooth meadow grass (Poa pratensis), Festuca species, bents (Agrostis species), and cock's-foot (Dactylis glomerata), false brome (Brachypodium sylvaticum), downy oat-grass and Helictotrichon pubescens. Less specific records of Poa, Bromus, Festuca, Milium, Brachypodium, Lolium, Avena, Alopecurus and Anthoxanthum.
Adults feed on nectar from a wide spectrum of plants including Centaurea, Cirsium, Leontodon, Erica, Rubus, Heracleum, Eupatorium, (sensu lato) Origanum, Senecio, Scabiosa, Succisa, Ligustrum and Filipendula.
