metallic blue - jasmine moth (30)
|Yesterday i bought a led headlight, then i used it on the night for shooting night photos.i took lots of in-flight shots also. This one is so beautiful moth that i never met until yesterday.|
This is a Jasmine moth - palpita unionalis
On aperture priority mode; F7,1 - (1/60 chosen by the camera's program) with -2 exposure.
- Adult: moth triangular shape in repose. Colour usually very pale, whitish. Wings semi-transparent and satin-like. Fore wings have brown markings, with two black spots in the middle. Wingspan 30 mm.
- Egg: flattened oval, yellowish-white, finely reticulated. 1 mm long, 0.5 mm wide.
- Larva: pale yellow body at hatching, becoming an increasingly green. 3 pairs of small setae sited laterally on each segment. At full development, the caterpillar measures 18 to 20 mm long.
- pupa: brown, slightly roughened; 12 to 16 mm long, 3 to 4 mm wide.
- Host plants: olive, as well as jasmine (Jasminum), privet (Ligustrum), ash (Fraxinus), arbutus (Arbutus unedo).
- The first adults appear at the beginning of spring. They are active at night and mate from the second day. Pairing lasts 4 to 6 hours and may be repeated many times.
The egg-laying period spreads over 11 to 30 days, depending on the season. The female dies immediately afterwards.
- The female lays about 600 eggs, usually singly, on the upper or lower surface of foliage.
The egg hatches after 3 to 20 days, depending on the temperature, the lower threshold for development being 9°C.
- Larval development lasts 18 to 25 days. The caterpillars feed on young foliage sited at the end of branches, at first scouring one surface, then cutting the lamina.
Before pupation, the caterpillar constructs a shelter by spinning several leaves together with silken threads.
The species has 2 or 3 generations each year.
Winter is passed as larvae.
Under normal conditions, the caterpillars are not numerous, and the damage they cause is economically insignificant. However, in nurseries, they may prevent the healthy formation of plants.
First-instar larvae at first scour the parenchyma of the underside of leaves. When older, the caterpillars cause tears in the foliage and may destroy terminal buds.
Second-generation caterpillars attack developing olives, eating them sometimes down to the stone.
