As I pointed out in one of my other blogs, I recently went to a u-pick farm. But instead of vegetables, I brought home photographs.

The sunflowers were glorious.

But of course, I spotted the grasshopper.

Wait, why does it have its left antenna down? In the previous photograph the antennae were up.

Oh. It's walking forward. Where is it going?

Perhaps it's going to continue snacking on the sunflower petals, because that seems to be where its left antenna is aimed.

Who knew grasshoppers used their antennae for GPS?

Let's take a look at a couple of photographs sent in by my cousin.

How did she ever spot this mostly green grasshopper hiding on a green plant?

Looks a lot different close up! Can you see the bright yellow semi-lunar process at the "knee joint" of the hind legs? (See previous post about grasshoppers for details).

This species has an unusual common name:  obscure bird grasshopper,  Schistocerca obscura.

Turns out the plant is unusual, too. Called the citronella plant or mosquito plant geranium, Pelargonium citrosum, it is a scented geranium that smells like another plant, citronella. Citronella is supposed to chase away mosquitoes, although there's some question whether the scented geranium has the same effect.

In any case, a scented geranium that smells like citronella evidently does not chase away grasshoppers.

Grasshoppers are moving in Arizona right now.

One of the most common species is the native pallid-winged grasshopper, Trimerotropis pallidipennis.

It can be difficult to identify grasshoppers because members of a single species vary a lot in color. The two grasshoppers in the photographs are within a few feet of each other, but notice how much darker the top one's wing bands are (it isn't just the lighting). Grasshoppers often blend into the background so well that you don't see them until they jump and fly.

Pallid grasshoppers feed on desert grasses and when the grasses dry up, they move or "disperse" to areas with more food. According to this article, pallid grasshoppers have been found flying at altitudes of 3000-5000 feet for long distances. In one record in 1966 pallid grasshoppers from the western United States were found in Hawaii. That's a long flight!

Are grasshoppers still active where you live? What colors do you see?
