- The adult of the Poor Knights weevil, Hadramphus
pittospori, has been recorded as living
for 3 years: most adults of weevil species
of the world
do not live more than 1 year.
- The adult is 16-20 mm long.
- The 6 larval stages last about 1 year, and
grow inside their host plant karo (Pittosporum crassifolium).
- The pupal stage lasts about 3 weeks, then
the adult hatches.
- The long adult life of these weevils is unusual.
It is perhaps one explanation why populations
of large-sized weevils related to this species
are so badly affected
by introduced predators such as rodents.
