Seven 'no-regret' actions could rescue insects on the road to extinction, a new roadmap for conservation says, helping ecosystems even where a lack of research means scientists cannot prove benefits to individual species.

High up in the mountains of Montana's Glacier National Park, there are two species of insect that only a fly fishermen or entomologist would probably recognize. Known as stoneflies, these aquatic bugs are similar to dragonflies and mayflies in that they spend part of their lives underwater before emerging onto the land, where they transform into winged adults less than a half inch long. However, unlike those other species, stoneflies do their thing only where cold, clean waters flow.

Creepy-crawlies are among the oldest life forms on this planet. Before dinosaurs ever walked the earth, insects were certainly already there. Some estimates date their origins to 400 million years ago. They're also extremely successful. Of the 7 to 8 million species documented on Earth, around three quarters are likely bugs.

But several insect species could disappear for good in the next few decades and that would have serious consequences for humans.

The rapid and dangerous decline of the insect population in the United States — often called an "insect apocalypse" by scientists — has largely been driven by an increase in the toxicity of U.S. agriculture caused by the use of neonicotinoid pesticides, according to a study published Tuesday in the journal PLOS One.

When it comes to problems caused by ticks, Lyme disease hogs a lot of the limelight. But various tick species carry and transmit a collection of other pathogens, some of which cause serious, even fatal, conditions.

It's that time of year: Mosquitoes and ticks are out in full force, and so are all the latest bug repellent products claiming to keep them at bay. So what bug repellent ingredients do Environmental Working Group (EWG) scientists recommend for kids? Our top picks are DEET, Picaridin and IR3535. These ingredients have low safety concerns and offer a high level of protection from a variety of biting insects and ticks.

More than 40 percent of insects could go extinct globally in the next few decades. So why did the U.S. Environmental Protection Agency (EPA) last week OK the 'emergency' use of the bee-killing pesticide sulfoxaflor on 13.9 million acres?

EcoWatch teamed up with Center for Biological Diversity via EcoWatch Live on Facebook to find out why. Environmental Health Director and Senior Attorney Lori Ann Burd explained how there is a loophole in the The Federal Insecticide, Fungicide, and Rodenticide Act under section 18, "that allows for entities and states to request emergency exemptions to spraying pesticides where they otherwise wouldn't be allowed to spray."
