Banded dragonfly

The banded dragonfly (オニヤンマ, Oniyanma) is an insect found in all of the games. It is rare, extremely fast and difficult to capture, since it travels in a straight line and won't stop to turn around. Except in, it is much more easier to capture as it can now stop to turn around and fly forward again, like it is with other dragonflies. With the exception that it along with the Petaltail Dragonfly can fly forward a bit faster than other dragonflies. It can be found in the months of July and August, during the day between the hours of 8 am and 5 pm.

Donating to the Museum
Upon donation to the Museum, Blathers will say:

In Wild World
"Hoo! You caught a banded dragonfly! Most impressive. Rather difficult, was it? Bit of a hairy fellow, wot? I say, some cosmetic plucking would really help..."

In City Folk
"Banded dragonflies are rather flashy... Just look at those piercing green eyes. The black and yellow body! Not to mention their sheer size and--OH, HORRORS! The beast is looking right at me! Look away, fiend!"

It can be found in the first terrace of the insect exhibit, flying near the small pool of water near the flowers. It shares its pool with the Darner Dragonfly.

In New Leaf
Upon being donated, the dragonfly can be found in the first room of the bug exhibit flying around the pond and occasionally resting on the fence. The exhibit has this to say about the Banded Dragonfly:

"Banded Dragonflies have black-and-yellow-striped bodies and bright-green eyes. They are large and can fly quite fast. They have strong jaws, so it might be painful if you get bitten. Their larval stage lasts two to four years, where they live near water, feeding on tadpoles and small fish."
