 BeeSource.com | POV | AHB | FABIS Manual - Fast Africanized Bee Identification System
In such a case, forewing length or fresh weight alone at a probability of Africanization of 0.99 or greater (PA 0.99) would be sufficient to identify a sample as Africanized.
Carefully remove the forewing from the bee, so that the entire forewing is obtained, if care is not taken, the wing often breaks, leaving the base on the bee, and the correct length cannot then be measured.
Forewings are not fastened directly to single coverslips with transparent tape because the adhesive on the tape blurs the wingtip and it often cannot be seen clearly.

 Genus Lycaena Copper Butterfly Wing Posters
As you study the ventral wing pattern of a resting butterfly, you'll notice the pattern often smoothly translates from the hindwing to the visible tip portion of the forewing.
In contrast, the covered portion of the forewing lacks the patternation and is often more brightly colored making for a disorienting flash of color as the butterfly launches into flight.
Oudemans' principle can also be observed on the forewing patterns where design element align between the fore and hind wings when the butterfly is displaying its dorsal surfaces.

 Insect wing - Wikipedia, the free encyclopedia
In Hemiptera (true bugs), the forewings may be hardened, though to a lesser extent than in the beetles.
In a number of other orders, the forewings may occasionally be modified for protection, and this usually occurs in conjunction with the loss or reduction of the hindwings (i.e., in flightless insects).
In a few grasshoppers, the sound-producing structures function only when the wings are flapping, with the forewings and hindwings hitting one another, and in some Lepidoptera (e.g., Cracker butterflies), sound is produced by the forewings striking one another at the peak of the upstroke.

The mean forewing length was 22 mm, the median (half the species had forewings less than this, half more) length 12 mm, and the mode (the forewing length shared by most of the species) was 6 mm.
We have noted the species names of the insects with forewing lengths equal to or greater than 50 mm and those with forewing lengths less than or equal to 2 mm on Figure 9.

 Found: the flying lizards’ missing lift - life - 12 October 2005 - New Scientist
The pterosaur’s wing membrane stretched between its fore and hind limbs, with the outer part of the leading edge and the wingtip supported by an enormously elongated “finger”.
But three-dimensionally preserved wrist fragments from fossils found in the UK led some researchers to believe pterosaurs were able to direct the pteroid forward and downward in flight, creating a broad forewing.
And thanks to the forewing’s steep camber, this lift was attainable at unexpectedly high “angles of attack” — the angle the wing bites into the airflow - as would be necessary from a standing start.
