Grasshoppers

Red-legged Grasshopper (Melanoplus femurrubrum)

Going for a walk in the long grass yesterday, every step I took, a couple of these fellows jumped out of my way. Usually they are quite hard to photograph but this lady obliged me while she was sunning herself on a log. You can tell she is female by the tapered abdomen and the tips of her ovipositor. A male has a rounded tail. Perhaps she didn't mind me taking her picture because she was partially blind. Her left compound eye looks quite deformed.

When reviewing the photographs at home, I was amazed at how completely covered in fine hairs she is. These insect hairs are called setae. Even her well armoured head and thorax are covered in fine hairs. These setae provide the sense of touch to the insect even though she is covered in a chitinous exoskeleton.

I find the mouthes of insects to be their strangest parts. I rarely am able to get a good look at what is going on down there. The antenna like palps around the mouth of this grasshopper have the greatest "ick factor" for me. I'm used to antennas; they sort of make sense as great big external nostrils, but four extra external tongues for tasting and manipulating food is four too many.

As I walked along I saw a couple of grasshoppers almost fall prey to a banded argiope. Unfortunately for the spider I spooked him and he broke off wrapping up his meal and went back to guard the center of his web. This allowed the grasshoppers time to disentangle themselves and make their escape. Below are a couple of other predators of grasshoppers: the only black and yellow garden spider I've seen all year and a great black wasp. The light reflecting off the wings of the great-black wasp was much bluer in person.

On the Basswood

Red-banded Leafhopper (Graphocephala coccinea)

These pretty red and green plant bugs are only about 5mm long so they often go unnoticed even though they aren't terribly shy or uncommon.

Jagged-Ambush Bug (Genus Phymata)

I wish all my insect pictures were in focus like this. Jagged ambush bugs are cooperative subjects.

Japanese Beetle(Popillia japonica)

I didn't notice this guy had some friends with him when I took the picture

Banded Argiope(Argiope trifasciata)

There are very few orb-weaver spiders about. A couple of seasons ago the tall grass was full of them; this is only the second I've noticed this August. I wonder what has changed, or if it just goes in cycles.

I find the structure of this spider's web quite interesting; not only does it have the zig-zagged stabilimentum below it like the black-and-yellow garden spider, it also covers the central area of the web in a very fine, almost transparent, film of silk.

Sand Cherries

There were about a dozen sand cherry bushes planted in 2009. They are poorly chosen for the location as Sand Cherries prefer a sandy or rocky location. They suffer from browsing on by the meadow voles and because they are a low bush, they have a hard time competing against the grasses and vetches. the plants have survived but have not prospered. This is the first year with a significant berry crop. The berries are actually not that bad; they are juicy and sweet, although a bit tart. There are recipes on-line for sand cherry jelly.

The Japanese beetles are pretty bad this year. They particularly like to attack basswood and grape vines where they skeletonize the leaves. The above picture is the first time I've noticed them attacking sand cherries.

Song sparrow on the sumac

This song sparrow was keeping an eye on me and calling out to his mate as I was walking along past this clump of sumac yesterday. His mate was answering but I couldn't locate her.

This has been a very good year for the trees with plenty of rain. A couple of sumacs in the 2009 area are sending out root suckers that can shoot up six feet while your back is turned. This clump the sparrow is sitting on is threatening to overwhelm a basswood and a couple of small spruce trees. It gives a hint of what the area will be like in a couple of years when the trees fill in the canopy. A couple of maple trees planted in 2009 have branches touching but for the most part it is the poplar and sumac suckers that are filling in the gaps.

White Admiral

White Admiral (Limenitis arthemis)

I haven't seen too many large butterflies this year. I haven't seen one Monarch. Lately though, I've noticed a few White Admirals like this one which is warming itself on a lilac leaf.
