Caloptilia honoratella

(Rebel, 1914)291a / 15.0131

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 has now colonized the UK with breeding proven.
The first proven breeding record in the county was in 2024, with the discovery of early mines on the upperside of Sycamore leaves at Purdis Farm, Ipswich on 28/08/2024 (N. Sherman).

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 silvery blotch mine with many extrusions between two veins on the upper surface of a Sycamore leaf, unlike Caloptilia rufipennella which makes a brownish mine on the lower surface of the leaf. Both species move out to roll a leaf lobe, so leaf mine records of early mines only will be accepted with a photo.

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

Determination by Genitalia Examination (gen. det.) Required

Mine: Either the leaf or a good photograph required
