The Brenton blue (scientific name: Orachrysops niobe) is a very special type of butterfly. It belongs to the family Lycaenidae, which includes many small butterflies. This butterfly is endemic, meaning it is found naturally only in South Africa. It is also listed as critically endangered, which means it is at a very high risk of disappearing forever.

About the Brenton Blue Butterfly
The Brenton blue is a small butterfly. Its wingspan (how wide its wings spread) is usually between 24 and 38 millimeters for males. Females can be a bit larger, with a wingspan of 22 to 42 millimeters. These butterflies usually fly during two main periods each year. You can spot them from October to November and again from February to March. This means they have two groups of new butterflies (called generations) born each year.
The Life of a Brenton Blue Caterpillar
Like all butterflies, the Brenton blue starts its life as a tiny larva, or caterpillar. These caterpillars have a very specific diet. When they are very young (in their first two instars, or growth stages), they eat the leaves of a plant called Indigofera erecta. As they grow bigger, they move on to eating the rootstock of the same plant.
You can often find these caterpillars hiding in small holes at the bottom of their host plant. Interestingly, they have a special relationship with ants. A type of ant called Camponotus baynei actually looks after the caterpillars. This is a fascinating partnership in nature!
Discovery and Conservation Efforts
The Brenton blue butterfly was first discovered in 1858. It was found by a scientist named Roland Trimen near a town called Knysna in the Western Cape Province of South Africa. After its first discovery, the butterfly was not seen again for a very long time.
Rediscovery and Early Challenges
In 1977, Dr. Jonathan Ball from Cape Town found a new group of Brenton blue butterflies. This population was located at Nature's Valley, about 50 kilometers east of Knysna. Sadly, this group of butterflies died out during the 1980s.
Then, in 1991, another important discovery was made. Ernest Pringle found a new colony of Brenton blue butterflies at Brenton-on-Sea. This was a very exciting moment!
Saving the Brenton Blue's Home
The land where this new butterfly colony lived was planned for a housing development. This would have destroyed the butterfly's habitat and likely led to its extinction. A big public campaign was started to save the species. Because of these efforts, the South African Government stepped in. In July 2003, they bought the land and turned it into a Special Nature Reserve. This reserve was created specifically to protect the Brenton blue butterfly.
Protecting the Future
Today, the Special Nature Reserve at Brenton is managed by an organization called CapeNature. They work with a special committee and use research to help the butterflies survive. A lot of important research has been done by Dave Edge from Knysna. His studies looked at the entire life cycle of the Brenton blue. He also studied everything that affects its survival, like the geology (the rocks and soil), the microclimate (small-scale weather patterns), the types of plants growing there, and how the butterflies interact with ants (myrmecophily). Understanding these factors is key to protecting this rare and beautiful butterfly for future generations.
