Egg: The dense mix of black and pale yellow pigment imparted a greenish tint to this egg (A). The longest I have had this egg prior to hatching is 2 days, but it has not been collected in an early development stage. Incubation is likely 3-4 days.
Larva: The newly hatched larva has the oil globule centrally placed in the yolksac (B, see also FIA4). The 2-day larva retains the pigment pattern of the egg (C).
