What was the original color of the peppered moth?
From Light to Dark Moths
Moth collectors in England noted that most peppered moths collected in the early 1800’s were
light gray peppered with bits of black
. Many years later most of the moths collected were almost completely black. Most of the peppered moths collected in the early 1800s were the light form.
Why did the peppered moth change Colour?
Eggs from light moths developed into light moths and dark moth eggs turned to dark adults. The dark color was
caused by a mutation in the DNA of a single moth
, and the mutated gene had been passed to all its offspring. This explained why the moths were dark, but not why the dark moths were taking over.

with moths placed on tree trunks showed that birds did indeed find moths based on the colour of the bark of trees

Are luna moths rare?
Luna moths are not rare
, but are rarely seen due to their very brief (7–10 day) adult lives and nocturnal flying time. As with all giant silk moths, the adults only have vestigial mouthparts and no digestive system and therefore do not eat in their adult form, instead relying on energy they stored up as caterpillars.
