The Giant Silver Bullet (Porogonognathellus dubius) is one of the biggest springtails available on the market. Their long, silver bodies vary in color from dark grey/silver to light yellowish/silver and their antennae is nearly as long as their body. A very active species that is fun to watch and have around.

They enjoy surface, wood sections of the vivarium and are pretty hefty eaters so they will make a great addition to many vivariums, terrariums, bioactive enclosures, reptile enclosures, etc.

They will work well in semi-arid environments as surface dwelling clean up crew (CuC).

This species is shipped in a 2oz container with a small amount of substrate and moist paper towel for safe travel. 

Every order includes a MI Beneficials, custom 3" vinyl Giant Silver Bullet sticker!
