Caloptilia honoratella
Pale Maple Stilt

(Rebel, 1914)291a / 15.0131
=Pale Maple Slender

Morley’s Final Catalogue: Not listed.

Recent Status: First British record taken in Surrey in 2017, with the second during April 2019 in Kent. The third British record was taken in Suffolk during September 2019. More Suffolk records followed in 2020 including the first for VC26 (Woolpit, P.Bryant). This species has spread rapidly westwards across Europe and could colonize the UK and may in fact have already done so.

Life Style: The moth is possibly double brooded and comes to light. The moth hibernates and can be found all year round. The larvae feed on Acer pseudoplanatus and A. monspessulanum. They are also noted to be xenophagous.

Identification: The moth is a deep cream colour with brown markings. There is a ferruginous tint on the tornus and on the side of the thorax. Some specimens, especially the summer brood can look similar to Caloptilia hemidactylella, particularly the females so moths should be retained, photographed and dissected. The larvae create a blotch mine between two veins before moving out to roll a leaf lobe. Three such rolled cones are produced.

Verification Grade Comment: Very similar to hemidactylella and dissection will be required for most specimens.

Determination by Genitalia Examination (gen. det.) Required

Mine: Moth needs to be reared and, in some cases, possibly dissected.
