Umbonia crassicornis - Thorn Treehopper
Crassicornis is actually Latin for thick horn
11/22/2014 - Awesome camouflage. At a normal viewing distance they look like thorns on a tree until you get close and they begin walking around...
From Wiki:
Thorn bugs, due to their unusual appearance, have long interested naturalists. They are best known for their enlarged and ornate pronotum, which most often resembles thorns, apparently to aid camouflage. In some species, the pronotum is a horn-like extension, but can form more bizarre shapes. The specialised pronotum (or helmet) may not be simply an expansion of the prothoracic sclerite, but a fused pair of dorsal appendages of the first thoracic segment.
These may be serial homologues of insect wings, which are dorsal appendages of the second and/or third thoracic segments. Evidence for this theory includes the development of the helmet, which arises as a pair of appendages attached to each side of the dorsal prothorax by an articulation with muscles and a flexible membrane that allow it to be mobile. Also, the same genes are involved in development of the helmet and the wings.
For some reason, this type of treehopper can easily be found feeding on senduduk plants. And for this shot i took the low angle shot to give a different perspective of the insect.
When insects moult they not only shed their "exoskeleton" they also shed systems attached to the exoskeleton. This photo of a buffalo treehopper nymph cast skin shows the trachea still attached on the interior.

Membracis Mexicana is a treehopper, member of the family Membracidae, a group of insects related to the cicadas and the leafhoppers. Treehoppers come in a variety of colors. There are many genera and each has a color and pattern variation or region of dominance. The protrusion, or 'horn', at the top of the head mimics a thorn and helps conceal the insect from predators when resting among plants. The bright coloration of some species may be another form of defense, giving predators pause when considering an attack on an insect with such alarming colors. The subject in the picture measures around 7mm.
Always a great pleasure to encounter these little beauties!!

Started to look at bridge cameras to find a replacement.... my word! What a mine field! How on earth does one choose??? I want one which uses AA batteries. Any recommendations??
Treehoppers can attract a variety of mutualists, and commensals which feed on the sugary exudate known as honeydew. Smallest and most surprising was this tiny predaceous mite, which I assumed was feeding on the still tinier, newly hatched treehopper nymphs, until it got up on its hind legs and stole some honeydew, evading patrolling ants by scurrying underneath the legs of the treehoppers.

Starting to see more and more insects in my garden. Excited to make a new find today. I have seen this bug many times but never the nymph. I have found that hoppers seem to really like the variety of yarrow growing in the garden.
Treehoppers (more precisely typical treehoppers to distinguish them from the Aetalionidae) and thorn bugs are members of the family Membracidae, a group of insects related to the cicadas and the leafhoppers. There are about 3,200 species of treehoppers in over 600 genera. They are found on all continents except Antarctica, although there are only three species in Europe.
They are best known for their enlarged and ornate pronotum, which most often resembles thorns, apparently to aid camouflage. But in some species, the pronotum grows to a horn-like extension, and even more bizarre and hard-to-describe shapes are also found.

This is tiny (5-7mm) and some type of treehopper, but I don't know which one. I spotted it in my backyard in McCall, Idaho.
Treehoppers are insects related to cicadas and leafhoppers. Most treehoppers have a highly modified pronotum on the back, in this case forming several hollow spines, which makes it unpalatable for potential predators and thereby gives it an advantage in the struggle for survival. Treehoppers feed on plant sap which is rich in sugar. In this video the sucking mouthparts of the treehopper have penetrated the vein of a leaf.

Treehoper are best known for their enlarged and ornate pronotum, which most often resembles thorns. Some reference said it is apparently to aid camouflage. But personally i dont see any camouflage value about it. It just make the insect more visible. In some species, the pronotum grows to a horn-like extension, and even more bizarre and hard-to-describe shapes are also found. Some theory described the pronotum as an organ that emit sound to attract potential mate from far away.
Treehoppers pierce plant stems with their beaks, and feed upon sap. The immatures like this one can frequently be found on herbaceous shrubs and grasses, whereas the adults more often frequent hardwood tree species. This treehopper stay on that ‘susur batang’ plant for three days for feeding, before dissapear on the fourth day because of heavy rain.

This is a Treehopper from the Amazon rainforest of Ecuador in the family Membracidae. Treehoppers are insects related to cicadas and leafhoppers. Most treehoppers have a highly modified pronotum on the back, in this case camouflaged as the thorn of a plant. Treehoppers feed on plant sap which is rich in sugar.
