Napi is closely related to the Mountain Green-veined White (P. bryoniae). For observations on the differences between these species, please see the bryoniae page. Napi is polyvoltine (multiple brooded) with three broods per annum, and possibly a fourth.
|The first brood male is very similar to bryoniae. The first brood female is quite heavily suffused (see 4570) and the summer brood (second generation) rather more cleanly marked (see 16184). I believe that 2529 is a second brood specimen of the southern European subspecies meridionalis, rather larger than the nominate form, and quite lightly marked.|

a first brood female, with the characteristic heavily suffused upf.
a summer brood female napi. I originally had this on the page for the Large White (P. brassicae) because that is what it clearly looked like, and I did not give it sufficient attention. The main reason for this, which I find surprising, is that I don't think I had previously seen a second generation female napi upperside, or at least, not knowingly. It is not a common species in Var. The dark apical mark looked good for brassicae as did the two black spots, and the absence of any real "green" or dusted veins. The illustration of second generation female napi in T&L shows the apical mark as rather fragmenting around veins 4-6 at the margins rather than the solid area as in 16184. However, the brassicae apical mark is solid black, whereas 16184 is rather greyer, and the brassicae apical mark is also smooth where it joins the costa, whereas 16184 has a pronounced "shoulder". 16184 also looks very clean and "white", but the lesson, for me at least, is always to look closely even if the identification seems obvious. Thanks to Tim Cowles for bringing this to my notice.

|26580||M||a summer brood male, puddling. It is of the subspecies meridionalis, as indicated by the pale yellow colour and light dusting of grey scales principally around the cell area.||1400|
|47922||M||a first brood male with rather lighter dusting around the veins than would be expected for a male (compare 47930).||60|
|47930||M||a first brood male with typically heavy dusting around the veins.||60|
|47829||F||a first brood female with rather heavier dusting around the veins than the illustration in T&L. There are two white unh patches indicating an absence of yellow scales, but this may be natural as there is no indication of any damage to the wing.||60|
a female meridionalis of the summer brood. The unh ground colour is very pale creamy-white and the grey scaling around the cell area is very light.
