Unfortunately, this idea isn’t going to work.

Lenses and mirrors can’t focus a diffuse source to a sharp point. They are also reciprocal; any light that can move one way through an optical system can also move the other way. As a result, you can’t use a lens or mirror to heat something beyond the temperature of the light source. The meet for of energy is always from the hot thing to the cold thing.

For the sun, that limit is almost 6000K, so you can do some damage. For fireflies, not so much.
