A beautiful, colourful moth, previously mistaken for over a century, has been revealed as a new species by entomologist Dr Peter Huemer of the Tyrolean State Museum Ferdinandeum in Innsbruck, Austria.

Described in the open-access journal Alpine Entomology, the new species, now officially named Carcina ingridmariae, had long been overlooked due to its close resemblance to the widespread oak carcina (Carcina quercana), a moth familiar across Europe and first described in 1775.

Despite its vibrant pink and yellow hues, Carcina ingridmariae escaped detection until advances in DNA barcoding revealed significant genetic differences of more than 6% from its lookalike relative. Subsequent analysis of the insects’ sexual organs confirmed the molecular findings, leading to the revelation that two distinct species have been hiding in plain sight.

The new species has a wingspan of about 2 cm, and is found across the eastern Mediterranean, from Croatia and Greece to Cyprus and Turkey. Its larvae likely feed on various oak species, similar to its counterpart. However, dedicated studies on its biology and distribution remain ongoing.

In recognition of enduring support throughout his career, Dr Huemer dedicated the discovery to his wife, Ingrid Maria, naming the moth after her on their 42nd wedding anniversary.

Huemer, who has described more than 200 species from Europe over 35 years said: “It is without doubt the prettiest species I have encountered in my long scientific career, even though it is still unnamed.” It was therefore “obvious” to Huemer that the new species should be given his wife’s name.
