Dozens of new insect species discovered at Fundy National Park

The recently renamed murder hornet may want to have a discussion about branding with some of the newly discovered species in Fundy National Park — like the shadowy psyllid-killer, the four-toothed mason wasp or the jagged ambush bug. 

Those are just some of the 50 insect species that were identified for the first time in the park in 2021, according to park officials. 

But despite their often-creepy-sounding names, none of the new species is of concern to local scientists.

In fact, entomologist and University of New Brunswick biology professor Stephen Heard said the discovery of so many new-to-the-park insects is good news.

"The vast majority of those new insects are good. They're insects that are part of the natural environment."

And, he said, many of them have probably been around for a long time without being officially noticed by scientists. 

"We know way too little about insects," said Heard, who was not involved in the Fundy project.

"And so those may be new species that have been attracted because of [the park's] work on the pollinator garden. They may have been species that have always been there we didn't know about."

Heard said it's not unusual for new insect species to move through New Brunswick, and the vast majority of them are not problematic. 

"Most of these species that we're talking about here are natural insects that just hadn't been recorded in Fundy before," he said. "We didn't know they were there, and they've popped up and that's great."

Going through Fundy's list of new species, Heard said, there were several that were unknown to him, including every single one of the fly species.

The list also includes bees, beetles, moths, wasps and butterflies. More than half of all the new species were identified in the park's pollinator garden, a 400-square-metre area that includes about 80 native plant species.

Pollinators can also include birds, but Neil Vinson, resource management officer for Fundy National Park, said no bird species were added to the list in 2021. 

While none of the species is considered invasive, if some of the newly identified insects are indeed new to the park, their arrival may change things for some other species.
