22.005 Prays peregrina Agassiz, 2007
< back

 

Food Plant: Ruta chalepensis (Fringed Rue), R.graveolens (Common Rue)

Egg: underside the leaf, away from the edge

Mine: Continuously brooded or possibly four generations: April-May; July-August; September; October-November

Notes: The moth was discovered in London in 2003- 2007(Agassiz, 2007) and subsequently found in urban locations in the south east of England by 2016 (Agassiz & Kiddle, 2016). The life history was unknown until Plant (2016) was able to elucidate this. The first instar larvae mine within the upper surface of a leaf and exit on the upper side. Subsequent larval instars mine the leaves full depth ( top photo) and move frequently to other leaves. The final instar larva may mine a leaf or feed externally (bottom photo). The pupa is formed in loosely spun leaves and hangs head down, attached by the cremaster. Pupation lasts around 7 days. The newly emerged adults drop to the ground when disturbed.

Data: x.2016, Bishop's Stortford, Hertfordshire, VC20
