The Lime Hawkmoth, Mimas tiliae, is a member of the large Sphingidae family of Hawkmoths.

It’s found in areas of deciduous woodland throughout much of the southern half of England and Europe.

It has a wingspan of up to approximately 80 mm and flies in a single generation from May to July in northern regions with a second generation in warmer parts of its range.

Despite having variable brown and green ground colouring to the forewings it’s an easily recognisable species.

Females generally having a brown ground colour to the forewing while males tend to be greener. The central, irregular shaped, dark bar is commonly broken but may be complete or occasionally absent.

Adult Lime Hawkmoths don’t feed.

Both males and females are attracted to light.

The normally browner females can be reliably identified by their swollen and straighter abdomen when compared to the slimmer and upward curving abdomen of the males.

Photographs of the Lime Hawkmoths shown are of different coloured forms attracted to light in south west England.

More Hawkmoth information and sightings from around the world can be seen in the Hawkmoth galleries, species pages
and British caterpillar gallery.

Lime Hawkmoth life cycle, Mimas tiliae

Eggs are laid in small batches on the larval foodplant – a variety of deciduous leaves including lime, birch, elm and alder (ref Porters – see recommended reference books).

Females attracted to light readily lay eggs and the hatching larvae are easily reared through.

Eggs hatch within 7-10 days depending on temperature.

The caterpillars can be found throughout the summer and into September.

The fully grown caterpillars pupate in the soil and overwinter as a pupa.

Emergence occurs in May.

In southern Europe there are two generations – May and August (ref A.R Pittaway – see recommended reference books)

Lime Hawkmoth prepupating caterpillar, Mimas tiliae

The prepupating caterpillars are brownish grey, sprinkled with white tubercles.

These prepupating caterpillars are commonly recorded in late summer on urban pavements lined with lime trees when wandering in search of a place to pupate

The pupae may be found buried just below the surface of the soil beneath trees of the larval foodplant.

The pupae overwinter with the adult Hawkmoth emerging in May.
