The increase in the number of black snails can. best be explained by

As far as I know about black snails is the fact that the Black Mystery belongs to the genus Pomacea,  Ampullariidae family. This family is also often called Apple Snail, and it contains a nearly 120 different species of snails. I know that increase in the number of black snails can best be explained by the high teperature in which black snails are. It's the main reason of their reproduction.

the eggs of the insects should be the first thing collected at the scene.
