Occupies a wide range of habitats and has a preference for warm localities , including savanna, grassland and open patches in forest.

The flight is fast and specimens are difficult to follow when in flight, often returning briefly to a favourite perch and frequently settle on grass stems. Often the hindwings are opened at a wider angle than the forewings. Both sexes feed from flowers and males mud-puddle. Often frequents gardens with flowering shrubs. Males establish territories in grassy patches using grass stems or low bushes as perches. Territories may be contiguous and the resident males of adjacent territories may spend much time chasing each other out of each other’s territories. The species is on the wing throughout the year but somewhat scarcer from May to September.Adults have long proboscises and are avid flower-visitors - appear very attracted to Plumbago.
Eggs are laid singly on grasses - This skipper is expected to be present wherever its food-plants occur.

Larval food:
• Ehrharta erecta Lam. (Poaceae)
• Pennisetum clandestinum Chiov.
• Themeda triandra Forssk. (Poaceae)
• Cynodon species (Bermuda Grass or Dog’s Tooth Grass).

Black-necked Agama (Acanthocercus atricollis)

They often nod their heads in display and appear to only come to the ground to cross to another tree or high point.They remain shy and wary always keeping a tree trunk or branch between themselves and danger. They can open their mouths wide, revealing an orange colour inside. They are not poisonous. They sleep at night in a hollow branch or unpeeling bark. Breeding males have more massive heads than females, and also develop swollen, scarred tail bases from fighting. The female lays 5-14 oval, soft-shelled eggs (10-21 x 22-28 rnm) in a hole dug in moist soil.
