![]() ![]() Prey species are relatively well defended during the day but “rather helpless at night,” she says, because it takes time for a sleeping insect to rouse enough to defend itself. Even without human transport, however, candy-striped spiders were observed ballooning and rappelling between insect bedrooms, surreptitiously securing sleeping targets with sticky silk.Ĭandy-striped spiders are not choosy about what they eat, preying on about 250 species, mainly bees and wasps. Sure enough, spiders, sensing slow food, climbed stalks to do their deeds. ![]() They also engineered predatory opportunities, introducing spiders to the base of vegetation where insects were sleeping topside. This was not their only previously recorded hunting strategy, however. Bristowe, had noted in the 1930s how this species lurks by its web, ready to pounce and hurl sticky threads after sensing vibrations. This grisly scene prompted the two researchers to take a closer look.įirst, they checked to see if other scientists had documented candy-striped nocturnal killing of sleeping insects. The smoking gun was the discovery of numerous sleeping wasps entombed in web, their innards sucked dry. McCann discovered mass carnage being carried out by candy-stripers during his morning photo shoots on the beach. While working on black widow spider research on the Tsawout First Nation territory on Vancouver Island in Canada, Dr. McCann is an avid macro photographer with a penchant for snagging beauty shots of snoozing bugs on dead vegetation during predawn hours. Her colleague Sean McCann, also an arachnologist who was then at Scarborough, first suspected the spiders’ clandestine habits.ĭr. She says these common spiders, native to Europe but now widespread in the United States and Canada, are known for doing “fairly normal web-building spider stuff,” and for the genes that cause their stripy features, but their active hunting of big prey at night had escaped notice. One of them, Catherine Scott, an arachnologist, conducted this research while working on her doctorate at the University of Toronto, Scarborough. Two scientists published their discovery Friday in the journal Ecology. New research reveals that two species of candy-striped spider have secret night lives, leaving their cobwebs to carry out violent predation after dark. Candy-stripers of the eight-legged variety, however, appear not so benevolent. If you're willing to sacrifice the fleeting in favor of the long term, you'll build loyalty and profit.įor more ways to build loyalty for your brand from the inside out, call Martha at hospitals, candy stripers are selfless volunteers. Never favor quantity over quality because that devalues both aspects of your brand: internal and external. Would Groucho be a good fit for your brand? His personality might attract more of what you really want, or it might cause a deadly overdose. Reward great customers and attract quality prospects by selectively using specials and sales promotions. The original customers may move on to find something else that's really special. But do it too often and the luster of the brand becomes tarnished. It can bring in a rush of revenue at key times. The lure of a big retail sales promotion that offers a deep discount or gift with purchase.When the offer expires, the money is gone-and so are those customers. There's no loyalty, just the desire for a quick buck. But this "hot money" only lasts as long as the term and the promotional rate. ![]() ![]()
