some die during embryonic stage
some die during first instar larval stage
some die during second instar larval stage
Homozygotes die as first to second instar larvae. They can live for up to 7 days before dying. In addition, many homozygotes probably die as embryos or young first instar larvae.
Lethal phase is during the first to second larval instar stages.
