Garden Leaf-mining Results for 24-09

325 Phyllonorycter mespilella
 A new species for VC30, right under my nose. Confirmed a few days later (D.V. Manning) by means of a vacated pupal case on the underside of the leaf. The food plant pictured is Conference Pear (Pyrus communis). In the wild it feeds on Service Tree (Sorbus torminalis) and Wild Pear (Pyrus pyraster). But is an extremely scarce species with relatively few records.

Pupae- image of cremaster (tail end) 
"The hooks at the tail end of the pupa (cremaster) are somewhat similar
in many species of Phyllonorycter sp. Fortunately they differ noticeably between mespilella and blancardella.
I am certain that you had mespilella, and John Langmaid (the national expert) has now agreed."
