Due to a lack of research and
information on L. pustuloides we do not know exactly
what they eat, but from some simple extractions we can gather a
general idea of what they eat. Since they are tiny woodland
creatures living in damp leaf litter we can guess that they are
herbivores using their radulas to scrape up any number of edible
materials from the leaves and dirt. This material could include
any number of algae, fungi, or decaying plant material. We can
also speculate that calcium is an important resource to these
snails as their shell is composed of calcium carbonate which
means they must be able to take in large enough amounts to
maintain the strength of their shells and be able to add on new
shell as they grow.
Here is some basic information on this
snail's Reproduction.
