[Note Guidelines] Photographer's Note
Grasshoppers are herbivorous insects of the suborder Caelifera in the order Orthoptera. To distinguish them from bush crickets or katydids, they are sometimes referred to as short-horned grasshoppers. Species that change color and behaviour at high population densities are called locusts.

The grasshopper's reproductive system consists of the gonads, the ducts which carry sexual products to the exterior, and accessory glands. In males, the testes consist of a number of follicles which hold the spermatocytes as they mature and form packets of elongated spermatozoa. After they are liberated in bundles, these spermatozoa accumulate in the vesicula seminalis
In females, each ovary consists of ovarioles. These converge upon the two oviducts, which unite to create a common oviduct which carries ripe eggs. Each of the ovarioles consists of a germarium (a mass of cells that form oocytes, nurse cells, and follicular cells) and a series of follicles. The nurse cells nourish the oocytes during early growth stages, and the follicular cells provide materials for the yolk and make the eggshell (chorion).


Six stages of development, from newly-hatched nymph to fully-winged adult. (Melanoplus sanguinipes)During reproduction, the male grasshopper introduces sperm into the vagina through its aedeagus (reproductive organ), and inserts its spermatophore, a package containing the sperm, into the female's ovipositor. The sperm enters the eggs through fine canals called micropyles. The female then lays the fertilized egg pod, using her ovipositor and abdomen to insert the eggs about one to two inches underground, although they can also be laid in plant roots or even manure. The egg pod contains several dozens of tightly-packed eggs that look like thin rice grains. The eggs stay there through the winter, and hatch when the weather has warmed sufficiently. In temperate zones, many grasshoppers spend most of their life as eggs through the "cooler" months (up to 9 months) and the active states (young and adult grasshoppers) live only up to three months. The first nymph to hatch tunnels up through the ground, and the rest follow. Grasshoppers develop through stages and progressively get larger in body and wing size. This development is referred to as hemimetabolous or incomplete metamorphosis since the young are rather similar to the adult.

Saludos Luis52.

Hola Luis,
Que maravilla de macro!
Los detalles son asombrosamente nítidos, conseguiste una excelente iluminación con el flash de relleno.
Los detalles y colores del saltamente lucen tan bien detallados y con el foco apropiado.
El fondo de color burgoña funciona de maravilla y resalta mas aún los verdes del insecto.
Felicitaciones y gracias por compartir la foto.
Un gran saludo,

Hi Luis,
You captured fine detail of this grasshopper.
Great color.
Perhaps composition would be enhansed by the hopper off center a bit to the right.

Just appreciating this wonderful shot from you. I am on a tour and internet connection comes at a premium here, hence doing a short job. Sorry.
