This species is at first glance similar to several other hairstreak species, but it has a characteristic blue spot on the underside, hence its name. It can often be ubiquitous in favourable habitats where individuals mob certain flowers in search of nectar. I have found it to be surprisingly approachable whilst feeding. Occasionally other closely related species can possess a small amount of blue scaling in a similar position to the current species, however it is never as large as the blue patch found on the Blue-spot Hairstreak. It also has a stronger white band on the underside than some of its relatives.
