Moth madness at Pasadena festival symptom of spruce budworm battle in N.L.

This year's Pasadena Days-Humber Valley Strawberry Festival in Pasadena included a magical, horrible, strangely beautiful concert event, as spruce budworm moths descended in the thousands.

"It literally looked like it was a blizzard. It was a snowstorm," said performer Vanessa Newman, a member of the Corner Brook band Merrymaker, who took a sip of water at one point in her set and immediately spit it out, realizing at least one moth was dead in there.

The moths moved around overhead lights like murmurations of starlings into the night. A white tent was darkened by moths coating the outside.

"They were on our instruments, in our hair, flying in our faces. But you know what? The crowd was great, the crowd stuck around the whole night. Right until the very end it was a really big crowd," she told CBC Radio's On the Go.

The three singers in her band "discovered a whole new level of concentration," she said, as they tried to keep moths from their mouths and eyes.

While an irritation to working performers, Newman said it was striking as a natural display.

"It was actually an amazing thing to see. I've never seen anything like it," she said.

It was a very particular moment in time for the insects. Spruce budworm only live about two weeks after reaching the adult stage of their lifecycle, as moths. They tend to mature around mid-July to August.

The sheer numbers in Pasadena are a reflection of the spruce budworm outbreak Parks Canada notes was long expected and "even a few years overdue," based on cyclical events, before numbers began to tick up a few years ago.

The province is now grappling with the rise, and is expected to be for years yet. Per the federal government, the exact impact of the current outbreak can't be assessed yet, but trees will continue to die for at least three years after the outbreak has collapsed.

Outbreaks of spruce budworm can run more than a decade. The insect can be particularly damaging as a caterpillar, chewing through tree needles but also buds of new tree growth. After a few years of ravaging by spruce budworm, whole stands of trees can succumb.

There are economic considerations there. A notorious outbreak in the 1970s into the 1980s, for instance, destroyed the equivalent of about a 25-year wood supply in Newfoundland and Labrador. There are also forest management and safety considerations, with so much dead wood in the wilderness, acting as fuel for wildfires.

Already, in the current multi-year outbreak, provincial forestry plans governing wood available for harvesting in forestry operations have started to increase what's available in areas where spruce budworm has returned in number.

"It was here last year as well, especially up in Gros Morne National Park, but this year ... it's just gone crazy," said Lloyd Hollett, owner of the Newfoundland Insectarium in Reidville in western Newfoundland.
