About the Colorado Hairstreak

The Colorado hairstreak is a small butterfly that grows to only about 25 mm in length. Its wings are black with iridescent blue and gold bands, giving it its shimmering appearance.

The butterfly is native to the Northern Southwest, mostly found within the hills and canyons at elevations of 6,500 and 7,500 feet. It primarily feeds on the leaves of the Gambel Oak and is completely dependent on the tree.

Physical Appearance

The Colorado hairstreak is a beautiful and striking butterfly with iridescent blue-green wings. Its markings are mostly golden or yellow, which gives it an almost golden aura when in flight. When fully grown, it measures about 25 mm in length, making it one of the smallest butterflies in Colorado.

Despite its size, the Colorado hairstreak is known to be quite a territorial butterfly, fiercely guarding its territory against other insects and animals. Its dependence on Gambel Oak also makes the insect vulnerable to environmental changes that could threaten its survival.

Life Cycle

Like other butterflies, the Colorado hairstreak undergoes a complete metamorphosis as it develops from an egg to a larva and finally into an adult butterfly. The female lays her eggs directly on the leaves of Gambel Oak, where the larvae will feed until they are ready to pupate.

Once hatched, the Colorado hairstreak caterpillar will feed on the leaves of Gambel Oak and shed its skin several times as it grows. Once fully grown, it develops a hard case around its body before finally pupating and emerging as a beautiful adult butterfly several weeks later.

Diet and Habits

The Colorado hairstreak’s primary diet consists of the leaves of Gambel Oak, a deciduous oak tree native to the Colorado highlands. Because it spends much of its life feeding on this one type of tree, the insect is extremely susceptible to changes in its habitat and environment.

The butterflies live in colonies that make it easier to find a mate. Although lovely, the butterfly is also known to be very territorial, fiercely defending its territory against other insects and animals. It is a fast flier, often seen chasing off others trying to invade its home.

Since then, Coloradans have continued to celebrate their state insect and all that it stands for. It’s a true testament to the state’s natural beauty and diversity and a symbol of Coloradan pride.
