Hymenoptera (which means “joined wings”) have two pairs of membranous wings that, when flying, join together with a series of miniature hooks called hamuli. These ingenious devices help the insect fly more efficiently. The social wasp, honeybee, bumblebee and ant are all part of the Hymenoptera order.
The wings of butterflies or Lepidoptera (which means "scaly wings") are covered with rows of small scales that resemble tiles on a roof. The slightest contact with the insects’ wings will leave a fine powder on your fingertips. This powder is made of detached scales.
