Insects are a class of invertebrates within the arthropod phylum that have a chitinous exoskeleton, a three-part body, three pairs of jointed legs, compound eyes and one pair of antennae. http://bit.ly/1tvBxTu

tsetse fly (genus Glossina), any member of a genus of bloodsucking
flies in the housefly family, Muscidae (order Diptera), that occur only
in Africa and transmit sleeping sickness in humans. They also
transmit a similar disease called nagana in domestic animals. Tsetse
flies have mandibles modified into bladelike structures used to
pierce skin. They readily feed on the blood of humans, domestic
animals, and wild game. The widespread presence of the tsetse has
inhibited human settlement and agriculture in large areas of sub-Saharan Africa.
All 21 tsetse species are similar in appearance. They are robust, sparsely bristled flies that are
usually larger than their relative, the housefly. They range from 6 to 16 mm (0.2 to 0.6 inch) in
length. Tsetses are rather drab in appearance, with colour varying from yellowish brown to dark
brown, and with a gray thorax that often has dark markings. The abdomen may be banded. The
stiff, piercing mouthparts, directed downward as the fly bites, are held horizontally at other
times. While resting, the wings are held flat over the back. A bristlelike appendage (arista) on
each antenna bears one row of long, branched hairs, differentiating the tsetse fly from all
other flies.

Cat fleas, Ctenocephalides felis, are the most common
ectoparasite on domestic cats and dogs (Figure 1). Dog fleas, C.
canis,look like cat fleas but are rare in California. Sticktight
fleas, Echidnophaga gallinacea, are commonly found on ground
squirrels and poultry; the females firmly attach themselves
along the ears and eyes of their host (Figure 2). They can
become a problem with pets that roam. The ground squirrel flea,
Oropsylla montana, is found on ground squirrels and is the vector of
sylvatic plague in California. However, fleas on cats or dogs in California most likely are cat fleas.

A new study shows that more than 40 percent of "kissing bugs" collected
by researchers in Tucson carry a parasite that can cause a disease that
kills tens of thousands of people a year in Central and South America.
But while the number of bugs hosting the single-cell parasite that causes
Chagas disease is much higher in the southern Arizona city than earlier
thought, no human infections have been traced to bites that occurred in
the state.
That may mean doctors are not looking for a disease that is rare in the
U.S. But it is more likely that the triatomine insects don't act the same way as their cousins to
the south, or that the disease is a different strain, said Carolina Reisenman, a University of
Arizona research biologist. She co-authored the study, which is to be published in the March
edition of the Centers for Disease Control and Prevention journal Emerging Infectious Diseases.

There are over 2500 different species of mosquitoes
throughout the world of which 150 species occur in the
United States. 52 species occur in California, and 19 species
occur in Alameda County. In the course of the District's
operation about 10 species are commonly found in the
County. Eight of the species account for over 99% of
complaints from the public.
Each of the species has a scientific name that is latin, such
as Culex tarsalis. These names are used in a descriptive
manner so that the name tells something about this particular
mosquito. Some species have what is called "common names“
as well as scientific names, such as Anopheles freeborni, the
"Western malaria mosquito".

At least 19 people have been stung to death by hornets –
which may include the world's largest hornet species Vespa
mandarinia -- in China's central Shaanxi province in the
last three months, according to the city government of
Ankang, the apparent epicenter of a recent spate of
fatalities and injuries.
A total of 583 people in the area have been stung by hornets
since July 1, say city officials. Seventy victims are still recovering in hospitals.
