|Common Name||Scientific Name||Found||Lifespan|
|Nanai||Raiateana knowlesi||Parts of the Serua and, Nadroga/ Navosa provinces on the main island of Viti Levu||2 Weeks|
Nanai has only been recorded on Viti Levu. The Nanai is of great significance to a particular clan in the Navosa Province, where all the chiefly daughters of that particular clan are accorded the title -“Rokonai”.The word”Roko” is a chiefly title given to male and female chiefs in some parts of Fiji. The word”nai” is a rare delicacy for this clan.

Lifecycle of a Fiji Cicada
Early on when the eggs are laid deep in tree branches and later on as young nymphs within the first year, before falling and burrowing into the ground for the next 7 long years. In the eighth year, around the beginning of the wet season, it is believed, rising temperatures signals the Nanai to move upwards above ground. Millions of Nanai emerge during this season but only for one to two months at the most It is a brief and noisy invasion of the forests, but an event awaited eagerly by villagers in several provinces of Viti Levu who consider the Nanai a delicacy for gourmets.

Nanai is a sought-after food, especially in the Navosa province where the adults are collected as they emerge from their final nymphal shells and tied together in chains and cooked. lt is usually cooked in bamboo stems before it is served with coconut milk. The taste is more or less like prawns roasted over charcoal. Women also use Nanai for bait when they go out fishing.

Butterflies are among nature’s most beautiful gifts to mankind. They have been admired and studied for centuries. Even the most uninterested observer of the natural world can identify a butterfly and will, as likely as not, pause to watch a nearby colourful butterfly. Currently, 46 native and one introduced species of butterfly are known from Fiji, Fiji’s butterflies belong to five families and five of the species are considered as endemic species and so found only in Fiji.

Fiji has several species of Jewel or Buprestid beetles, which are among the most colourful of its beetle population. None of them are common unless one knows where to look for them. In spite of their brilliant colours or perhaps because of it, as their spectacular colours surprisingly only help these beetles blend into their natural surroundings.

Dragonflies are perhaps the most attractive-looking insects after various butterflies and beetles, with their eyes and bodies coming in a veritable rainbow of different colours. They typically have an adult lifespan of between 1-9 months. The dragonflies’ distinctive visual characteristics are their wings typically they are entirely transparent, through all species have at least one coloured window at the front of each wing.
An adult dragonfly’s main diet consists of a variety of insects, they hunt their prey in a couple of ways…
- Many sit on a perch (territorial) and when something passes by they fly up to catch it. Successful or not, they usually then return to the same perch, or perhaps another favourite perch in the same area.
- Other species patrol up and down an area, and catch their prey in mid-flight, dragonflies have evolved amazing powers of flight, with four wings which can be operated independently, enabling them to forward and backwards. they are typically referred to as ‘mosquito hawks’ as they consume a large number of these harmful insects beneficial to humans, another reason for their popularity. flying without break and even eating while on the wing.
Like many other flying insects, dragonflies are unable to fly when their large flight muscles are cold, so if the temperature is below about 18 degrees Celsius they usually remain hidden in vegetation. Some darker dragonflies become darker when it’s cold, which helps them heat up if there’s any sunlight.
The different patterns of veins on the wings are the main way of distinguishing one family of dragonflies from the other.

In Fiji, 10 species of Moths have been described, they are among nature’s most accomplished mimics. Some moths are day fliers and would be easily mistaken for butterflies by the untrained eye.
The Sphingid (Hawk) Moths are found all year round (abundant during the warmer and wet months), they are the most interesting group of moths with their thick bodies and long fore wing, making them quite powerful flyers. They feed on blossom nectar through the proboscis that uncurls to reach the bottom of a flower tube.
|Coconut Stick Insect - Mimimata||The coconut stick insect is the most common stick insect in Fiji, and is unusual among stick insects in having wings, though they are very small and not particularly useful for flying. Females are bright green and about 7 inches (17cm) long, while males are light brown and rather smaller. They spend their lives attached to the rough underside of coconut leaflets.|
|Ucikau - Phasmid Cotylosoma dipneusticum||The Fijian stick insect is unique to Fiji, and has a ferocious appearance, with rows of vicious-looking thorn-like projections along the sides of its brown blotchy body and legs.|
|Ucidrau - Phasmid Chitoniscus feejeeanus||The leaf insect is very rare in Fiji, which is at the eastern extremity of its range, They are small – up to 4 inches (10cm) at most – and the body mimics green leaves in shape and colour, down to the presence of veins.|
|Ucikau Walking Stick - Hermarchus apollonius||The Giant stick insect is one of Fiji’s largest insects, attaining a length of 12 inches (25cm), particularly fond of guava trees.|
Stick insects (known as ucikau in Fijian, uci, meaning ‘to resemble ‘, plus kau, meaning ‘stick’) are one of nature’s experts at camouflage, evolving alongside the vegetation closely in which they reside, being stationary most of their lives, this evolutionary invisibility cloak protects them from known predators, with an additional ability if required to regenerate any lost limbs which may be lost through fight and flight.
They have long thin bodies, and long antennae, with some species having small wings. The majority of stick insects are females, which are normally larger than males, and capable of reproduction by themselves.
