Explanation of Names
At Words by William Whitaker, "collis" translates to "head and neck", while "margini" translates to "margin" or "border". This could be referring to the stripe on the head and thorax of this species.
Numbers
3 subspecies, with 2 of these occurring in the U.S.
Size
Males: 28-31 mm, females: 31-38 mm in length.
Identification
This slender, elongate grasshopper has a very pointed head and flattened, sword-shaped antennae. Thus, it superficially resembles grasshoppers in the subfamily Gomphocerinae, but is easily distinguished by the presence of a spur, or spine, between the front legs.

They are usually brownish with a whitish, yellow, or brown stripe from the eye to the base of the front legs. The head is as long as, or longer than, the pronotum. On top, the body may also be reddish or pinkish. The front wings are sharply pointed, extending 3-5 mm beyond the tip of the abdomen (1) (2).
Range
Southern U.S., Mexico, Belize, Honduras, Guatemala.
Habitat
Inhabits wet areas, and is usually found on emergent vegetation such as cattails and sedges.(1)
Season
Apparently found in any stage throughout the year. Adults tend to be common in early spring.
See Also
Stenacris vitreipennis is easily confused with Leptysma marginicollis (Serville), but in L. marginicollis the head is as long as, or longer than, the pronotum whereas in S. vitreipennis the head is shorter than the pronotum. The antennal segments, although flattened, are not nearly as wide as in L. marginicollis.
