...and Dwarves
The Western Pygmy Blue (Brephidium exilis) only measures half an inch (1.3 cm) across, the Leaf Miner Moth even less: 1/8 inch (0.3 cm). Their caterpillars live inside leaves.

The Sky Full of Butterflies
One of the biggest clouds of moving butterflies ever seen measured 250 miles (402 km) across. For a whole day every minute over a million butterflies flew past.
26,000 butterflies passing by every minute have been seen in Ceylon. At a movement of the Painted Lady (vanessa cardui) in California that took 3 days the number of butterflies seen during daylight was estimated 3 millions.

A Great Variety
There are about 20,000 species of butterflies, the moths are even more numerous: about 150,000 species of them can be counted all over the world.

Speedy
Some Hawk-Moths (Sphingidae) reach speeds up to 34 mph (54 km/h) when they fly. Some species of the Skippers family can do 37 mph (60 km/h).

Slow Development - Long Life
Some moths need up to 7 years to get a butterfly. Most of this time they spend as a pupa.
There are Arctic moths living 14 years as a caterpillar only being active a few weeks each summer. The adult, however, only lives for one short season. The brimstone butterfly has the longest lifetime of the adult butterflies: 9-10 months.

A Long Way
Death’s-head Hawks have been found in Iceland. This means the animals have flown nearly 500 miles (800km) over the sea without having a break.
