Pearl-Bordered Likeness, Greasy & Small Pearl-Bordered Fritillaries
Melitæa Athalia, M. Artemis & M. Silene
- Greasy Fritillary. Its deep brownish-yellow wings are crossed by black undulating lines and yellow spots, the hind wings showing three bands with six small black spots in the orange middle one. Named for the glistening, greased look of the under side, it feeds as a black spiny caterpillar on plantain and devil’s-bit scabious, and the butterfly haunts southern counties, reaching as far north as Durham.
- Small Pearl-Bordered Fritillary. Rather smaller than the greasy fritillary it resembles above, it is told apart beneath by the rust-brown hind wings, silvery central spots, and six silver triangles along the border. Its black spiny caterpillar, half its spines yellow, bears a pale side-stripe, and the butterfly is of frequent occurrence, appearing near Newcastle in early July and abundantly near Durham.
