Quite common and widely distributed in southern France, but not usually found in large numbers. It is distinguishable from other Melitaea species by the very large upf marginal lunule in s3 - other species may have a large-ish s3 lunule, but none have such a difference between s3 and adjacent ones as phoebe. The female is larger than the male and sometimes has a greyish suffusion. It has quite a wide altitude range, being found at 2000m plus, but is also widely distributed at low levels. It is an early emerger, one of the first fritillaries on the wing.
It is, in my experience, an extremely variable species, with some specimens very light orange and hardly marked, to quite dark with a large contrast between the bands (e.g. 7796), even from the same location and same time of year. It also seems to be quite prone to aberrations, two examples of which are shown on this page. |
The underside pattern is typical of the Melitaea family, as compared to those of the Mellicta family which bear greater upperside resemblance to phoebe. However, in 2010 the new European taxonomy was issued which groups the Mellicta fritillaries species under the Melitaea genus. A view of the underside should make identification straightforward, and the unh post-discal spaces each contain a large round centrally-positioned red spot.
In the past decade, it has been discovered that an almost-identical species Melitaea ogygia occurs in parts of eastern Europe and is believed to occur in Provence in France. Phoebe and ogygia are almost impossible to tell apart by studying the adults, but the larvae are significantly different. The only reference source I can locate is Tristan Lafranchis' recently-issued DVD-ROM. |

| 7796 | M |
a typical dark male, albeit with no spots in the uph post-discal orange spaces. |
1470 |
| 12038 | M |
a very orange specimen, with limited upf markings and very little colour contrast between the bands. |
1550 |
| 21671 | M |
an unusual aberration in that the margins are very wide and dark, and the discal regions are almost unmarked. 21651 is the underside, so it was bizarre on both surfaces. |
1400 |
| 22099 | M |
another unusual aberration, in that only the forewings are melanic, almost completely, but the hindwings are normal. As mentioned on other species pages, the early spring in southern France was unusually cold and wet and these aberrations seem to be the result. |
2020 |
| 22119 | M | a fairly normal male phoebe, perhaps rather lighter than average. The angle of the forewings shows the distinctive "shoulders". | 2020 |
| 24802 | M | a very fresh male, beautifully orange such that the paler marginal lunules stand out very clearly. | 280 |
| 26523 | M | a very lightly marked male, given the high altitude. | 1400 |
| 24431 | F | a mating pair, the lightly marked female on top with open wings as is often the case. | 700 |
| 10456 | F |
a dusky dark female, quite dull. The left upf wingtip is slightly malformed. |
1000 |
| 25744 | M | a typical underside. | 1080 |
| 26559 | M | a rather unusual underside in that the discal marks are rather elongated and slightly sagittate externally. The general colouring is quite beige. | 1400 |
| 26822 | M | a male underside, slightly unusual in that it is rather white. | 1700 |
| 21651 | M |
the underside of 21671, probably even more of an aberration than the upperside. |
1400 |
| 21309 | M |
this male seems unaware that just behind him a crab spider has another phoebe in its grasp. |
1320 |
| 7760 | F |
the female underside, very similar to the male underside. |
