Two-Spined Spur-Throat Grasshopper
melanoplus bispinosus
The Two-Spined Spur-Throat Grasshopper (Melanoplus bispinosus) is a fascinating member of the spur-throat grasshopper family, primarily active during the warm summer and autumn months. Characterized by its specialized feeding habits and remarkable jumping ability, this insect plays an important role in recycling plant matter within its grassland and prairie ecosystems. Like other members of the genus Melanoplus, it possesses a distinct spine or tubercle on the underside of its throat, which is a key trait of this diverse group of insects. Observers often encounter this species in sandy grasslands and agricultural margins, where its cryptically colored body provides near-perfect camouflage against dry weeds and soil. While it may appear as a simple garden hopper, its evolutionary adaptations for leaping and digesting complex plant defenses make it a highly successful survivor in arid, open landscapes.
Hábitat: Found in open sandy prairies, grasslands, pastures, and disturbed roadsides where sparse vegetation and loose soils are common.
Aspecto
This grasshopper typically ranges from 2 to 4 centimeters in length, showcasing a mottled grayish-brown to yellowish-tan base coloration. A prominent dark stripe runs from behind its compound eyes across the side of the pronotum. Its hind legs are particularly robust, featuring dark, oblique bands on the outer femur and blue or pale-blue tibiae with black-tipped spines. The male is distinguished by a pair of small, spine-like projections on the subgenital plate, giving the species its 'two-spined' common name.

Datos interesantes
In late autumn, females drill holes into the soil using their ovipositors to deposit egg pods that overwinter and hatch in spring.
The 'two-spined' identifier comes from two distinct small bumps or spine-like structures on the male's abdomen tip.
The common name 'spur-throat' refers to a tiny, peg-like projection located on the throat between their front legs.
