Bears emerging from hibernation
Bears are beginning to emerge from hibernation. Travel in groups of three of more, make noise and carry bear spray. Visitors must stay at least 100 yards from bears. More »
Insects are possibly the most important group of animals on the planet by playing key roles in food webs. They pollinate dazzling wildflowers, provide food for many animals, and act as decomposers and nutrient-recyclers. Amazingly, insects outnumber all of the other animals combined. In this region alone, there are over 10,000 different species.
Many flowering plants depend on a single insect species for pollination. Dazzling flowers like lupine, yellow-bells, phlox, sunflowers and the delicate Calypso Orchid rely on bees, beetles, and butterflies for survival. Plants use a large amount of energy to attract insects with bright colors and alluring scents to ensure survival.
The violet-colored lupine attracts bees in our park. Lupine, a member of the pea family, has a very complex flower structure. The two bottom petals are fused together to form a canoe-shaped pollen protector. When a bee lands, its body pushes the tip of the canoe-like petals down exposing the pollen as if opening a trap door. Pollen sticks to the bee's belly that is then carried to the next lupine. Only bees are the right size to open the hatch and pollinate lupine.
Thousands of animals rely on insects for energy and nutrition. Insects are the primary food for lizards, snakes, frogs, trout, and many birds including blue birds, chickadees, woodpeckers, thrushes, wrens, sparrows, dippers, jays, sapsuckers, and a few ducks. Even bears depend on insects. During fall, the massive grizzly feasts on the tiny Army Cutworm Moth. Swarms of cutworm moths migrate from the plains to the alpine to mate in fall. After mating, the moths die and grizzly bears roam the high peaks scooping up moths by the paw-full, an important pre-hibernation protein source. On the forested slopes below, both bear species feast on ant colonies and beetle larvae called grubs. If you see a log on the trail ripped to shreds, it might be where a bear enjoyed a snack.
Beetles are true workhorses of the forest acting as construction crews, recycling crews and sanitation crews. Bark beetles bore through conifer bark and chew elaborate tunnels on the wood underneath. Beetles break down woody plant material and recycle nutrients back to the soil. When an animal dies, carrion beetles recycle the valuable minerals in the body. Through tunneling, chewing and feeding beetles mix up the soil playing a major role in decomposition. Their activity helps the next generation of plants and animals to start anew.
Insects are fascinating, and you don't even have to drive to a national park to see them. Explore an undiscovered world in your own back yard.
Did You Know?
Did you know that Jenny and Leigh Lakes are named for the fur trapper “Beaver” Dick Leigh and his wife Jenny (not pictured)? Beaver Dick and Jenny assisted the Hayden party that explored the region in 1872. This couple impressed the explorers to the extent that they named the lakes in their honor.
