Appearance:\nIt has a rusty orange colour to the wings, upper body and the tips of the antennae. The body is silvery white below and it has a wingspan of 25–30 mm. This butterfly is very similar in appearance to the Essex skipper (Thymelicus lineola). In the small skipper, the undersides of the tips of the antennae are yellow orange, whereas they are black in the Essex skipper. The black area on the lower edge of the upper wings also differs. Like the other orange grass skippers the male has a distinctive black stripe made up of scent scales.\n\nLife cycle and food plants:\nEggs are laid loosely inside grass sheaths of the caterpillars food plants from July to August. The newly hatched caterpillars eat their own eggshell before entering hibernation individually in a protective cocoon of a grass sheath sealed with silk. In the spring the caterpillar begins feeding. The favoured food plant is Yorkshire fog (Holcus lanatus), although other recorded food plants include timothy (Phleum pratense), creeping soft grass (Holcus mollis), false brome (Brachypodium sylvaticum), meadow foxtail (Alopecurus pratensis) and cock's foot (Dactylis glomerata). The caterpillars pupate near the base of the food plant in June with the first adults on the wing at the end of June, a week or two before the first Essex skippers. They are strongly attracted to purple flowers such as thistles and knapweeds.\n\nDistribution:\nThis butterfly's range includes much of Europe (east to the Urals, including Ireland, Britain and Scandinavia, and includes north Africa and the Middle East. It is typically occurring where grass has grown tall.\n\nThis Picture is made during a Long Weekend in the South of Belgium in June 2019.

Nigella damascena, also known as Love-in-a-mist and Devil in the bush, is an annual garden flowering plant, which belongs to the buttercup family Ranunculaceae. Native to southern Europe, north Africa and south-west Asia, it is found on neglected, damp patches of land. Its common name “Love-in-a-mist” comes from the flowers being nestled in a ring of multifid, lacy bracts. The flowers, blooming in early summer, are most commonly different shades of blue, but can be white, pink or pale purple, with 5 to 25 petals.

Pyrgus malvae, the grizzled skipper, is a butterfly species from the family Hesperiidae. It is a small skipper (butterfly) with a chequered pattern on its wings that appears to be black and white. This butterfly can be found throughout Europe and is common in central and southern regions of England. The butterfly prefers three major types of habitat: woodland, grassland, and industrial. Eggs are laid on plants that will provide warmth and proper nutrition for development, such as A. euphoria. As larvae, their movement is usually restricted to a single plant, on which they will build tents, unless they move onto a second host plant. Larvae then spin cocoons, usually on the last host plant they have occupied, where they remain until spring. Upon emerging as adult butterflies, grizzled skippers are quite active during the day and tend to favour blue or violet-coloured plants for food. They also possess multiple methods of communication; for example, vibrations are used to communicate with ants, and chemical secretions play a role in mating. Exhibiting territorial behaviour, males apply perching and patrolling strategies to mate with a desired female.\nHabitat: \nAlthough grizzled skippers occupy three major forms of habitats, they tend to settle in environments with spring nectar plants, larval food plants (agrimony, creeping cinquefoil, wild strawberry, tormentil), ranker vegetation, and edges with scrub or woodland. Host plants are from the family Rosaceae with a focus on Agrimonia eupatoria as well as Potentilla. \nFlight Season: \nGrizzled skippers produce one brood per season and are in flight from the middle of March to the middle of July. \n\nThis Picture is made during a Vacation in Bulgaria in May 2018.

The Common Blue is the most widespread blue butterfly in Britain and Ireland and is found in a variety of grassy habitats.\nThe brightly coloured males are conspicuous but females are more secretive. The colour of the upperwings of females varies from almost completely brown in southern England to predominantly blue in western Ireland and Scotland, but the colour is variable within local populations with some striking examples. Unlike Adonis and Chalkhill Blues, the dark veins do not extend into white fringes of wing margin
