Worse Than a Bee Sting

Jerome has a skunk problem.  The critters are as common as rats and if you have one there's a neighbor with a live-trap to help correct the problem.  But stories are unique in details of people who have trapped one then walked up to the trap and gotten sprayed...y'gotta have some perspective dealing with them.
I "possessed" a de-scented skunk years ago in an old college dorm. One night I let it out of it's cage for a 2 AM saunter through some of the halls and a drunk coming in after the bars closed stood in front of it as it cobbled an awkward walk along the baseboards.  The skunk (not the late-night drunk) sunk its canines through the top and bottom of the drunk's big toe (sandals y'know) and kept cobbling without a pause.  When the drunk had first spotted the thing he exclaimed, "What a cute Kitty."  It obviously took offense at being so grossly misidentified.
It's a long, long way in miles and years from that college dorm but you always have to be precise in identifying a threat.  If you go wrong ID'ing such a distinct black/white critter the result may be worse than a bite.  
While certain insects and reptiles are  recognized by remarkable colors...not your common raccoons and opossums...part of the perspective depends on you...beware of Jerome...or beware of something that lives there.

Maybe She Will...Maybe She Won't

A big female crab spider about the size of a small quarter dollar.

Crab spiders or, more precisely, misusenoides formosipes, are found on flowers where they wait to ambush typical pollinators.
Popular thought says the spiders change color to match the flower they're on.  Fun!  This one was found  in a neighbors yard and the color match was so precise the camera had to define where the flower started and the spider ended.  
White crab spiders will sit in white Datura blossoms...yellow ones hide in...well...yellow blossoms.  
Two theories exist.  One is that when these spiders travel to a new location, a different flower of a different color, the spider's color will change in about a week.  The other theory postulates that they simply assume the color of the flower they were hatched on.
The result is probably academic...a female that changes color is fairly common.
Crab spiders make use of camouflage more than other spiders.  The color of the spider is adapted to the hunting terrain.
Because they sit in easily spotted places they become vulnerable prey.  When they spot a possible enemy they move quickly to the other side of their location or leave. 
Crab spiders are recognizable if you tease them. They spread their legs and move side ways...like a crab. 
Although crab spiders are fairly common, finding one might take some patience because they are often well camouflaged. If you want to find a crab/flower spider, try to think like a spider: Where would you sit if you wanted your prey to come to you?

It's a Prickly Life

When we drove a local gravel road the other day the visuals quickly changed from small town shops and restaurants to scrub desert, hills, ravines, endless views if you're up high . . . typical in rural Arizona.  

Wildlife was plentiful.  Hawks and golden eagles looked for mice and squirrels, and lotsa snakes that didn't like human companionship went about their business,  pushing these same mice and squirrels back into their burrows.

Flowers provided a carnival of color...prickly poppies, penstemons already tall, prickly pear in bloom.   

Prickly Poppies grow anywhere there's disturbed soil . . . roadsides, old garages, abandoned houses.  The attractive blossom belies the rest of  the plant. . . stems, leaves, and seed pods are covered with spines.
True to the poppy family the seeds provide a slight narcotic effect, if you're willing to endure working with the spine covered seed pod ( above,left....below, right/left).
Despite the wind that curled the petals a small butterfly negotiated its way to the flower, looking for nectar in all the meager places. 
 It doesn't take much to sustain a butterfly, but it was a lucky photo opportunity.  

Nectar attracts these pollinators but the attraction is momentary until they travel to the next flower . . .maybe another prickly poppy.
But...maybe not.
  
Next for the butterfly was another plant with spines.  Unlike the prickly poppy, the prickly pear has a stem that has morphed into a spongy, water storing pad and "leaves" that have evolved to water conserving spines.  The pads carry a waxy coating that prevents water loss.  Shallow roots absorb the minimal desert rainfall, exaggerated reproductive characteristics (flowers) attract pollinators.  
The drive for life takes many forms.

Colors of the Desert

We took a road-trip to Organ Pipe Cactus National Monument in the southwest part of Arizona, south of Ajo, close to the border.  After several days we drove north and east to Saguaro West National Park, up toward Eloy.  Following are some pics.
