The purple milkweed butterfly, which winters in the south of the island, passes over some 600m of motorway to reach its breeding ground in the north.
Many of the 11,500 butterflies that attempt the journey each hour do not reach safety, experts say.
Protective nets and ultra-violet lights will also be used to aid the insects.
The flies spend several years in a riverbed, in a nymph stage.
When they emerge in late May or early June for action-filled lives lasting about a week, they do so in a gossamer blizzard, numbering in the tens of thousands.
Snowstorms, the most powerful in more than 100 years, seized the Primorye Region near the Pacific in early March, creating high snow and making it difficult for tigers to hunt.
"A group of rescuers has been sent to the Yakovlevsky district to take the tiger back to taiga," an official of the Russian Natural Resources Ministry said, adding that the thick snow had forced the tiger to risk moving along cleared roads.
Neither the pilot nor the biologist was injured, but the moose was maimed by the spinning rotor and had to be euthanized, wildlife officials said.
"It just had to be one of those quirky circumstance. Even dealing with bears and goats and moose and wolves, this is pretty unusual and truly a very unique situation," said Doug Larsen, regional supervisor for the Division of Wildlife Conservation.
Since then, there have been hundreds of reports of animals seemingly foretelling catastrophe - not just minutes, but sometimes hours and even days before it occurred. These include tales of bizarre behaviour by wild beasts including elephants, antelopes, bats, rats and flamingos, plus stories of dogs refusing to go for their usual morning walk.
Could these creatures have sensed the massive earthquake that triggered the 2004 tsunami? It is an outlandish assertion, given that seismologists have so far failed to come up with any sign that a quake is imminent. Yet, for the same reason, the possibility animals might hold the answer cannot be ignored. After all, an advance warning system could save thousands or even millions of human lives.
In 24 states throughout the country, beekeepers have gone through similar shocks as their bees have been disappearing inexplicably at an alarming rate, threatening not only their livelihoods but also the production of numerous crops, including California almonds, one of the nation's most profitable.




Comment: While we cannot yet say what might be behind this strange phenomenon, there are two suspects in view: EM waves in the atmosphere - either natural or artificial - or some other kind of disruptive frequency such as cell-phone towers.
It would be an event of the utmost irony if our civilization's mad rush to have the latest gadgets brought the whole kit and kaboodle to its knees via starvation.
