other info :
Two or more broods are produced each year. The adult may be encountered at any time of the year, especially in the south of the range, where there may be three or four broods. It overwinters as an adult in a crevice among rocks, trees, and buildings. On very warm days it may emerge to feed in mid-winter.

Eggs

The glossy pale green eggs are spherical with a 1 mm diameter. They are said to look like the flower buds of the host plant Galium, and that is where the female lays them. They hatch 6 to 8 days after laying. Up to 200 eggs may be laid by one female, each on a separate plant.

Larvae

Newly hatched larvae are clear yellow, and in the second instar assume their green coloration.

The larva is green with two grey stripes bordered in cream along the sides and the horn at the rear end typical of sphingids. The horn is purplish red, changing to blue with an orange tip in the last instar. They feed fully exposed on the top of the host plant and rest in among a tangle of stems. Although dependent on warmth and sun, the larval stage can be as rapid as 20 days.

Pupae

The pupae are pale brownish with a prominent, keeled proboscis, and two sharp spines at the end of the cremaster. They are enclosed in loose silken cocoons among the host plant debris or on the ground among leaf litter.

Adults

The forewings are brown, with black wavy lines across them, and the hindwings are orange with a black edge. The abdomen is quite broad, with a fan-tail of setae at the end. The wingspan is 40–45 millimetres .

In the southern parts of its range, the Hummingbird Hawk-moth is highly active even when temperatures are high, and thoracic temperatures above 45 °C have been measured. This is among the highest recorded for hawkmoths, and near the limit for insect muscle activity.

You could probably crop off the top and right hand side ..... it would have greater impact
