Phigalia
Phigalia is a genus of geometer moths in the family Geometridae, established by Duponchel in 1829. Species in this genus are primarily North American and European, with several exhibiting distinctive life history traits including winter-emerging adults and, in some species, wingless females. The genus includes notable species such as the Spring Cankerworm (P. titea) and the Small Phigalia (P. strigataria), both of which are early-season defoliators of deciduous trees.
