Western Pondhawk


Pondhawks (Erythemis collocata) are members of the skimmer family, with similar looking Eastern and Western species.

The male Western Pondhawk, seen in the top picture, is a mixture of green and blue, indicating youth. In a week or so, both the thorax and abdomen will be a consistent light blue color.

Male Western Pondhawks look similar to Blue Dashers. The green nose and solid color thorax (whether early green or mature blue) represent good field identificaion marks to differentiate between the two species.

The female western pondhawk (Erythemis collocata) is green in color with the yellow or tan markings on the abdomen.

Golden tabby tigers

In addition, another recessive gene may create a very unusual "golden tabby" colour variation, sometimes known as "strawberry". Golden tabby tigers have light gold fur, pale legs and faint orange stripes. Their fur tends to be much thicker than normal There are extremely few golden tabby tigers in captivity, around 30 in all. Like white tigers, strawberry tigers are invariably at least part Bengal. Both white and golden tabby tigers tend to be larger than average Bengal tigers

Tiger Woods

born December 30, 1975) is an American professional golfer whose achievements to date rank him among the most successful golfers of all time. Currently the World No. 1, he was the highest-paid professional athlete in 2007, having earned an estimated $122 million from winnings and endorsements. According to Golf Digest, Woods made $769,440,709 from 1996 to 2007, and the magazine predicts that by 2010, Woods will become the world's first athlete to pass one billion dollars in earnings. Woods has won fourteen professional major golf championships, the second highest of any male player, and 65 PGA Tour events, third all time. He has more career major wins and career PGA Tour wins than any other active golfer. He is the youngest player to achieve the career Grand Slam, and the youngest and fastest to win 50 tournaments on tour.

white tiger

A white tiger is a tiger with a genetic condition that nearly eliminates pigment in the normally orange fur although they still have dark stripes. This occurs when a tiger inherits two copies of the recessive gene for the paler coloration: pink nose, pink paws, grey-mottled skin, ice-blue eyes, and white to cream-colored fur with black, grey, or chocolate-colored stripes. Mr. H.E. Scott of the Indian police gave this description of a captive white tiger's eyes-"The colorings of the eyes are very distinct. There is no well defined division between the yellow of the comex and the blue of the iris. The eyes in some lights are practically colorless merely showing the black pupil on a light yellow background (Another genetic condition also makes the stripes of the tiger very pale; white tigers of this type are called snow-white.)White tigers do not constitute a separate subspecies of their own and can breed with orange ones, although all of the resulting offspring will be heterozygous for the recessive white gene, and their fur will be orange. The only exception would be if the orange parent was itself already a heterozygous tiger, which would give each cub a 50% chance of being either double-recessive white or heterozygous orange

Common whitetail Dragonfly

Like many dragonfly species, the name of the dragonfly, the common whitetail, pretty much describes it.

Common whitetails (Plathemis lydia) are among the most ordinary dragonflies across the United States.

They are part of the better skimmer family, and merely one of two members of the Plathemis genus of whitetails.

The adult male, sports a white tail. The picture above shows a gray white abdomen and yellow spots on the rear of the head.

Females of the species split a similar abdomen pattern, without the white cover.

They can easily be mistaken for eight-spotted skimmers because they also contain eight spots on their wings, so the white spots the length of the sides of the abdomen serve as better field recognition clues.

Blue Dasher

The Blue Dasher (Pachydiplax longipennis) is wide all through the United States, along with being the sole representative of the Pachydiplax genus.

Males are characterized by blue eyes, a blue abdomen and white striped thorax.

Like many of the Libellulidae females, the female blue dasher is brown.

Leaf - cutter bees

• Leafcutter bees are native bees, significant as pollinators.

• Leafcutter bees are not violent and contain a mild sting that is used only when they are handled.

• Leafcutter bees cut the leaves of plants. The cut leaf fragments are used to shape nest cells.

• Leafcutter bees nest in soft, rotted wood or in the stems of big, pithy plants, such as roses.

Leafcutter bees are significant native insects of the western United States. They use cut leaf fragments to build their nest cells. They often are necessary pollinators of wild plants. Some leafcutter bees are even semi domesticated to help create alfalfa seed. However, their habit of leaf cutting, as well as their nesting in soft wood or plant stems, frequently attracts attention and concern.
