No, they’re not orange blueberries…

Also known as wild coffee because its fruits can be used as a substitute for coffee, late horse gentian’s orange fruits stand out in autumn woodlands.  I found a small group of these plants on the edge between prairie and woodland at our Rulo Bluffs Preserve a couple weeks ago.  They were pretty hard to miss – I saw them from about 20 yards away as I came up out of a deep wooded draw.  I was hoping to get some photos of the prairies before the sun went behind the nearby bluffs, but I couldn’t resist pausing a few moments to photograph this unique plant.

The plains lubber (Brachystola magna) is Nebraska’s largest grasshopper.  At about 2 1/4 inches long, and brightly colored, it’s hard to mistake for other species.  In fact, of the 108 grasshopper species in Nebraska, the plains lubber is the only one that is not in the family Acrididae.  Truly a unique individual.

Grasshoppers tend to have a bad reputation among many farmers and ranchers because they’re seen as competitors to livestock or as damaging feeders on crops.  In truth, only a handful of grasshopper species cause any significant “damage” to agricultural crops or pastures.  You’d think that a grasshopper the size of a lubber would eat an awful lot of grass, but in fact, the lubber primarily eats the leaves of wildflowers many people would consider weeds – especially annual sunflowers, but also kochia, hoary vervain, and prickly lettuce.  Hardly a pest, if you’re a rancher, though I hear it can sometimes be hard on cotton crops down south.

Lubbers are mostly found in the western portion of Nebraska, in mixed-grass and shortgrass prairie.  Because they have very short wings, they’re unable to fly, but are sometimes seen “migrating” on foot in large numbers.
