Egg: The tiny oil globule and lack of pigment in the developing embryo within the egg separates this species from all except LIIIE9. No picture of the egg is currently available. Incubation is about 24 hours. 

Larva: The NH larva usually lacks pigment (B), though a few small black pigment spots may be seen post-anus on a white background. The stocky build, and triangle of pale yellow blotches at, and posterior to the anus, in the 1-day larva, stand out in the identification of this species (C). By day 3 (D), black pigment has developed adjacent to the yellow spots, forming a vertical band through the body, similar to P. gibbosus (KIIIC1), while the rear yellow spot is reduced in size (D). B: NH, C: 1 day, D: 3 days (24°C).

This egg has only been recognised on 6 occasions, off Park Rynie. It bears so many characteristics of the anthiines that it is tentatively placed there. No barcode is available for a larva hatched from this egg.

As noted above, this egg was rarely seen at Park Rynie, and was not recognised in the DHM samples. Little can be gleaned from the spawning pattern (blue graph).Of the 14 occasions it was encounteed at Park Rynie, 19 eggs (59%) were in offshore samples and 13 inshore, indicating spawning inshore of kob. See Section 7.3 and Table 1 of the Introductory Notes, for more information on the linked samples.
