and life cycle—Wireworms
Common wireworm species require 3 to 4 years to complete
their life cycle. Most of the time is spent in the larval
stage, but all stages may be present at once during the growing
season. The larvae move up
and down in the soil in response to temperature and moisture.
Mature larvae form a pupation cell of soil particles; they
may pupate right away or remain in the cell over the winter,
pupating in the spring. Adults
that develop in the fall may also remain in pupation cells
over the winter. In spring and summer, adults burrow to
the surface. Both sexes are capable of flying to reach mates
and egg-laying sites. Females burrow
back into the soil to lay eggs.
