The main flight period of the Sinai baton blue, when the adults are active, is from May to mid-June. Due to its small size, the adult butterfly is relatively sedentary, rarely flying more than 50 metres (4). The adults of this species feed almost exclusively on the nectar of Sinai thyme (T. decussatus), but will also occasionally feed on nectar from other plants (2).
The female Sinai baton blue lays around 26 eggs on average, depositing each one individually on a Sinai thyme inflorescence. The tiny white eggs measure approximately 0.5 millimetres in diameter and hatch after a few days. The larval development stage is presumed to take approximately 21 days, during which time the larva goes through a series of moults. The larvae of the Sinai baton blue are relatively immobile, remaining on the plant on which the eggs were laid and feeding on its buds and flowers, before pupating in the soil below. The pupae remain in the soil over winter, hatching into adults in the following year (2) (5).
The caterpillars of the Sinai baton blue sometimes associate with ants, which protect and tend to them. In return, the caterpillars secrete sugary droplets that the ants consume (2).
