Lepidoptera Noctuidae Heliothinae
Specimen Helicoverpa armigera
At any stage of their life cycle, reliable differentiation of the two species requires laboratory examination, but the general description below holds for both species.

The eggs are approximately 0.5 mm in diameter and are white to brown in colour. Caterpillars pass through four developmental stages (instars) and ultimately reach 30 to 40 mm in length. The caterpillar’s body varies in colour from green, yellow, pink and red-brown, to almost black, and the head is usually pale brown. Several pale, fine, wavy, broken lines run along the body, and there is a broad cream stripe running along each side. In addition, there is often a single dark stripe along the middle of the back. Many minute spines cover the body surface and can be seen using a hand-lens; these are characteristic of these caterpillars. In addition, there are often dark, raised spots on the back, at the base of fine hairs.
The caterpillars pupate in the soil in a silk lined chamber. Pupae are 14-20 mm long, pale brown in colour with a tinge of green, turning darker brown as the moth develops within. The tip of the pupa bears two long (1.2-1.3 mm) straight spines.
Adult moths have a wing-span of 35 to 40 mm, and range in colour from green-grey to orange-brown. The forewings have a network of dark lines and a broad brown band that runs from front to back. The hindwings are paler, with a broad, dark brown border, brown veins, and a dark, comma-like marking in the middle.

Helicoverpa armigera.
El "taladro" es un lepidóptero polífago que ataca a numerosos cultivos como el maíz y la alubia. Estos insectos se alimentan de la planta excavando galerías en su interior.

Hi Nicolas

What a beautful and contrasting image!
The bright and vivid colors of the plant and the caterpillar look great against that dark (but not black) BG.
The details and textures are fantastic and teh diagonal composition is very beautiful.
Very well done!

Bravo and TFS

Hello Nicolas,
Maybe it's a Helicoverpa armigera (these caterpillars are quite variable in colour) or a different Heliothinae...

Best regards,
Dmitry

Amazing "decorations" on this caterpillar, Nicolas. The designs and colors are shown in sharp details and excellent light. I like the pose and the composition you chose. Very interesting-looking creature.
TFS : )

Great macro, excellent colours and very good details.
I like it very much.
Very well done!
Regards, Krzysztof.

Hello Nicolas,
very nice colors and details of this macro, good composition and you did well with the framing too, well done and TFS,
Nelson

Very nice. Good details and composition. colors, dop and lighting are nice. Good dark backgroung to isolate the subject.. allowing it to stand out.
details are great.. i can see the 'hairs' on the plant as well as the spikes on the caterpillar, even though it is not as sharp as i'd like it.
