Encontrado en una Nuez de Nogal
Camara Kodak DX6490 con Raynox DCR250. Flash difusor casero. F8 - 1/125

Spanish:
El ciclo de este insecto se desarrolla en los frutales de pepita y nogales, fundamentalmente.
Los daños los origina la fase de larva, se manifiestan como unas mordeduras en la epidermis del fruto. Luego viene el punto de penetración que se encuentran en el punto de contacto de dos frutos o con una hoja o en la cavidad de inserción o calicina. Las galerías originadas son en espiral ( al comienzo) donde se puede ver la larva de unos 2 - 3 mm y penetra en el corazón llegando hasta las pepitas que origina una caída de frutos.
El adulto es una mariposa oscura de unos 20 mm de envergadura y en las alas anteriores una mancha oval de color castaño en su extremo. Las larvas son de color rosa pálido o rojizo con la cabeza castaño oscuro y alcanzan hasta 15 a 20 mm de largo.
En general esta mariposa se puede alimentar de manzanas, peras, nueces, albaricoques y en ocasiones de melocotón y ciruela.
El número de generaciones puede llegar hasta tres. Los primeros adultos aparecen de mediados a finales de abril y se continúa su vuelo hasta septiembre.

Description
- Adult: Wingspan 16 to 19 mm. Very obvious and characteristic brown oval marking, surrounded by 2 shiny golden brown lines, tending towards the bronze, on the grey fore wings. Hind wings reddish brown, delicately ciliated.
- Eggs: 1 mm diameter. Circular, flattened, slightly swollen in the middle. Laid singly on the upper side of the leaf, on the fruit or twig. Milky-white at first, then, a few days later, with presence of a reddish ring at the periphery.
- Larva: 16 to 20 mm. Head dark brown; body pale pink to reddish. Abdominal prolegs, anal prolegs.
- Pupa: 10 to 12 mm. Yellow-brown to dark brown. Occuring in silky cocoon.
Biology
- Host plants: apricot, quince,walnut, pear, apple and sometimes peach and plum.
- Adult: medium longevity, 15 to 18 days. Active during the day at temperatures of >15°C.
- Fecundity: 30 to 50 eggs, on average.
- Eggs: time until hatching, 18 days at 15°C, and 6 at 25°C.
- Larva: developmental duration, 20 to 30 days.
- Pupa: developmental duration, 20 to 28 days.
Life Cycle
- 1 or 2 generations per year, sometimes 3.
- The eggs hatch at the end of May.
- The caterpillar first undergoes a so-called "wandering stage" (2 to 5 days. After a couple of exploratory bites, it penetrates a fruit where a second fruit or a leaf is touching, or at the stalk or stalk-eye. When development is completed, it leaves the fruit and weaves a cocoon in a sheltered spot. From then onwards, two developmental routes are possible: it will either pupate and give rise to a 2nd-generation of moth, or enter diapause. The caterpillars that become fully fed from August to October all enter diapause. They overwinter in cocoons hidden in cracks in the tree-trunk or in a natural shelter on the soil.
- Pupation in April.
- The adults emerge at the end of April, beginning of May. They mate and lay the eggs on leaves, twigs, or young fruits.
