I can think of at least two exceptions to this statment:
(1) In Cenorhabditis elegans (I hope that I spelled that right), parthenogenic
females do not require the presence of male stimulation to produce offspring.
(C. elegans is a self-fertilizing roundworm.)

(2) The behavior of the artificially produced Drosophila strain "lazy girl"
is altered in that the "lazy girls" repell male advances.
