Heterarthrus nemoratus (Fallén, 1808)
< back
ventral view
dorsal view


Food Plant: Betula spp. (Birch)

Mine: Summer

Notes: The older part of the mine is characteristically a red-brown colour and the mine contains little frass as the larva ejects it through a slit. The larva pupates in the mine in a disc structure. The larva is pale in colour and the prothorax has apale plates with a median sulcus. Ventrally the prothorax has the typical Heterarthrus 'collar', with further spots on the meso and metathorax.

Data: 11.vii.2006, Scolton Manor Country Park, near Haverfordwest, Pembrokeshire, VC 45
