What is the difference between Carbonaria and Insularia peppered moths?
The darkest melanic phenotype, named carbonaria, is nearly solid black and is easily distinguished from the much paler typical form (wild type) of the moth Phenotypes that are intermediate between typicals and carbonaria are called insularia
What did Dr Kettlewell want to find out?
During the 1950’s, Henry Bernard Davis Kettlewell ran a series of experiments and field studies to find out if natural selection had actually caused the rise of the dark peppered moth Dr He spent the rest of his life studying peppered moths and other moths known to turn dark through industrial melanism
Is Pepper made from moths?

What happened to peppered moths in the Industrial Revolution?
Scientists have discovered the specific mutation that famously turned moths black during the Industrial Revolution In an iconic evolutionary case study, a black form of the peppered moth rapidly took over in industrial parts of the UK during the 1800s, as soot blackened the tree trunks and walls of its habitat
Why are there more black moths than white moths?
He conducted a series of observations, fieldwork and aviary experiments, and found that his data fit his predictions: black moths were becoming more abundant because they were being better-camouflaged and predated less by birds in soot-covered areas compared to their newly exposed and vulnerable white counterparts
What do white moths turn into?
Small white moths, often called lawn moths, are a common sight in lawns and grasses throughout North America The moths themselves don’t cause a great deal of damage to grass and other plants, but their larvae do In larval form, these moths are small worms or caterpillars that collectively are called sod webworms
