Common Bluebottle

Fascinating facts about the Common Bluebottle

• The common bluebottle's wingspan ranges from 55 mm to 75 mm. Its upper wing surfaces are an opaque black, while the undersides are a dark brown colour. It inhabits moist low-level rainforests below 1600 m and is usually seen flying just above the tree canopy. This size and colour pattern allow it to blend with the shaded forest light during its rapid, low-level flight.
• The retinas of the common bluebottle contain fifteen distinct colour-detecting opsins, giving it a highly nuanced visual palette. This extensive set of photoreceptors supports the butterfly's famously quick flight and rapid reactions, enabling it to navigate the dappled light of the forest understory. Such visual acuity is especially useful when it darts among flowers for nectar or evades predators.
• Male common bluebottles often gather at the edges of puddles to sip moisture, a behaviour known as mud-puddling. At a single puddle, as many as eight males may be seen feeding together, sometimes alongside other insects. This congregating habit provides them with essential salts and nutrients that are scarce in their nectar diet, supporting reproduction and flight stamina.
• During migration in the Nilgiri hills it may represent as much as 5% of the butterfly count. This share is noted over a 72-hour period.
• The male bears a grey abdominal fold with a tuft of long, somewhat stiff white hairs. These hairs are a distinctive trait of the species.
