Gatekeeper
Pyronia tithonus
Butterfly
The Gatekeeper (Pyronia tithonus), also called the Hedge Brown, is a medium-sized orange-and-brown butterfly of the family Nymphalidae (subfamily Satyrinae), recognisable by the dark forewing spot enclosing two white pupils and, in males, a distinctive androconia patch (sex-brand) across the forewing. Adults are on the wing from July to August (occasionally from late June in warm or southerly conditions), favouring sheltered hedgerows, woodland edges, and scrubby field margins across Europe, with additional populations in Morocco and western Turkey. Larvae feed nocturnally on fine grasses including bents (Agrostis spp.), fescues (Festuca spp.), and meadow-grasses (Poa spp.). In gardens, adults nectar heavily on wild marjoram (Origanum vulgare), bramble, ragwort, and fleabane, making herb and wildflower plantings a reliable way to attract the species.
Plan for this species
Location-fit plant set for Chicago, IL: host and specialist plants first, then nectar, fruit, seed, foliage, and shelter plants that still fit the current and mid-century climate read.

Sheep fescue
Essential / Larval host plants
Wikipedia names the gatekeeper (Pyronia tithonus) first among the caterpillars that feed on this grass, and the gatekeeper record in this catalogue independently gives fescues among its larval foodplants. The practical consequence is a maintenance instruction rather than a planting one: gatekeeper larvae feed nocturnally on the leaves and overwinter small, so a sheep fescue planting that is sheared to the ground in autumn loses them. Leave rough tussocks standing through the winter at the sheltered, hedge-backed edges the adults patrol in July and August.
Red fescue
Essential / Larval host plants
Pyronia tithonus larvae feed on fine grasses including bents (Agrostis), fescues (Festuca) and meadow-grasses (Poa), and the adults favour sheltered hedgerows, woodland edges and scrubby margins, which is the half-shaded ground where red fescue is most often sown. Genus-level host record again, so plausible rather than documented. It is listed partly to make a point about this genus in the catalog: blue fescue (Festuca glauca) carries an empty wildlife list as an exotic ornamental, while red fescue across its native European range is a working larval host. Choosing between them is a wildlife decision as well as an aesthetic one.
Oregano
Supporting / Nectar plants
Wild marjoram (Origanum vulgare) is one of the gatekeeper's most consistently documented nectar sources; a garden study recorded satyrines visiting Origanum almost exclusively.
Butterfly bush
Supporting / Nectar plants
Short-tongued and partial to open flowers like marjoram; a garden study recorded zero gatekeeper visits to Buddleja against hundreds on Origanum, so buddleia is at most an incidental visit.

Range
Found across western, central, and southern Europe; absent from Scotland (bar occasional southern records), Scandinavia, and northern parts of the continent. Beyond Europe, the range extends to the Rif mountains of Morocco (North Africa), and to Turkey and the Caucasus in western Asia. Two subspecies are widely recognised - P. t. britanniae in the British Isles and P. t. tithonus across continental Europe - with P. t. distincta (Rothschild, 1933) described from Ketama, Morocco, whose status varies by authority.
