Geometridae, Ennominae Wingspan: 32-44mm. A local species occurring throughout the UK, but confined to established open broadleaf deciduous woodland mostly to the east of Cornwall. Its wing patterns are very similar to the other members of this Genus, but the ground colour is a distinctive pale buff-brown with darker orange-brown markings. As with the others, there are dark wing-tip areas appropriate to their colour shades. At rest this species hold their wings in a partially opened stance which looks quite attractive. The UK flight season is indicated as May / June with a possible second generation in July / August. In the South. However, in Cornwall, possibly due to under-recording, only small numbers have been seen from April to June.

Geometridae, Ennominae Wingspan 32-40mm. One of the most powerful "Thorn" species in the UK, it is a very fast flyer and not too easy to capture, even when attracted to light. A common species throughout the UK and it is found in mixed woodland mainly in central and eastern Cornwall. A very distinctive species with the bright yellow thorax, and, at rest, the wings are sharply swept back as shown above. The flight season in the UK is late July to mid October, with a peak occurring in August / September.

Geometridae, Ennominae Wingspan: 44mm. A common species here and also on the UK. It came to the trap throughout our stay, producing 22 specimens.

Geometridae, Ennominae Wingspan 28-46mm. A commonly occurring species throughout the UK, and widespread in Cornwall. Characteristically, it rests with its wings together butterfly fashion, and only on rare occasions would a glimpse of the upper side of the wings be visible, usually as it is fluttering around. This picture is one of those instances which has frozen the view to see it. One of the darker species of "Thorn", particularly because of the underside, it is unmistakable. As its common name implies, this is one of the first moth species appearing in, or even before, the early Spring. It has at least two generations each year. The UK flight season is quoted as mid February to May, and again in July to September, but in Cornwall individuals are possible from January to November, with slightly reduced numbers in June.

Geometridae, Ennominae Final Length 32mm. A common "Thorn" moth, with a larva which can mimic a bare twig shoot.
