While some plants are pre-disposed to certain bugs in the
wild, such as Sarracenias and wasps, N. ampullaria and ants,
etc., the basic rule seems to be that the size of the bug is
what matters. Bugs which are too big will escape, or if
they are caught, can rot the leaf, but typically the plants
can only catch bugs that are of a correct size.

Flytraps grow from a rhizome, which elongates over time.
Some people call these "bulbs". In the winter the flytrap
goes dormant. The leaves die back to the rhizome. All
my flytraps have gone dormant already. This dormancy is
required for the plant to come back bigger and better each
year. As for the plants in stores, they are often under-
watered, etoliated from lack of sun, etc. Flytraps require
lots of pure water, plus lots of sun, during their growth
cycle. They will respond with larger, more active, traps,
and a deep reddish colour inside the traps.
