Micros and Geometr are out early in the evening, when they should be taken with the net.
The third group of the 'Micros' is the Crambi, and contains about eighty species, arranged in four families.
Geometr and Micros may be taken from palings and tree trunks by day, or caught flying at dusk.
The Micros are abundant from early spring to late fall about shrubbery, in open fields, and along the edges of woods.
The Psychina and Micropterygina are included amongst the Micros by most modern authors.
