Moth/Giant Moth
Information
It's common to think that there's no difference between Moths and Giant Moths , but in fact there are a number of differences in their natural ecology and appearance. Giant Moths are the product of moths that were used in experiments in the Umbrella laboratories. They escaped and grew to huge proportions due to the T-Virus. For some reason, Giant Moths' wings haven't grown in proportion with the rest of their bodies, so they can only fly a few feet from the ground.
It's thought that before the Giant Moths reached their current size, they
had spread the effects of the T-Virus through a few different generations.
This has led to an increase in both the amount of phosphorous powder they
produce and its toxicity. Their larvae are referred to as Baby Moths, and even
in their infantile state, they possess a considerable amount of attack power.
When they sense a human nearby, they drop down from the ceiling and then
spray sticky, hard-to-escape mucous from their mouths to cover their prey.
Moths, on the other hand, were originally kept in Umbrella's Antarctic facility as
another kind of guinea pig. Like the Giant Moths, they grew to their current size
after becoming infected with the T-Virus. Their phosphorous powder also contains
a high level of toxicity, but unlike the Giant Moths, their wings have grown in perfect
proportion to the rest of their bodies. This allows Moths to bob and weave around a
target at will, before attacking by spreading their poisonous powder around the victim's
body. Also, their larvae grow as parasites from living organisms, so
they're constantly searching the perimeter of their nests to find
suitable hosts for their eggs.

Moths attack by spreading large amounts of poison powder throughout the air, which is fatal to any human prey who inhale it. Also, they go after their prey aggressively in an attempt to lay their eggs. (RE 2, RE CV)
Giant Moth
The Giant Moth's most notable characteristics are its unnaturally imbalanced wings and its large, pulsating abdomen. Because they can't fly very far off the ground, they're always dragging their enormous bellies around.
Giant Moth larvae. Their bodies are only 30 centimeters
or so, and their life force is rather weak. However, because so
many of them are incubated within their nests, the numbers
with which they attack their prey are nothing to sneeze at.
They're attracted to warm-blooded organisms.
