New Zealand’s Nocturnal VIP

Meet the huhu beetle, Prionoplus reticularis, New Zealand’s own longhorn with a swagger that says, I was born to be dramatic. This large, visually distinctive insect packs a striking presence, with adults growing up to about 5 cm long.

The huhu is endemic to New Zealand, meaning it’s basically the country’s own VIP guest. It doesn’t know the meaning of regional exclusivity and instead strolls across much of the land, climbing up to altitudes of around 1,400 meters. It’s the kind of beetle that doesn’t mind a trek to the high country or a late-night buzz around your porch light.

Larvae, Timber, and a Very Odd Menu

As an adult, the huhu has a perplexing dietary limitation: it cannot eat. Think of it as the life of the party that forgot to bring snacks. But fear not, this is where the larval phase earns its stripes.

The larvae dig into dead wood, doing their best impression of tiny, lumber-loving excavators. They primarily feed on gymnosperms such as rimu and Monterey pine, tunneling through wood with the determination of a seasoned carpenter.

As a larva, the huhu can grow to 5 to 7 cm, with a cylindrical, creamy appearance. During this stage, it is high in protein and fat, is edible, and has been described as tasting similar to peanut butter, which is not a sentence most beetles get written about them.

Culture, Ecology, and the Short Adult Encore

In Maori tradition, the larvae have been consumed either raw or cooked in a hangi. It’s a reminder that traditional diets often included a surprising variety of protein sources, and that the line between food and adventure can be delightfully blurry.

The adult huhu’s lifespan is roughly two weeks. Short, sweet, and loud with those long antennae, the adult huhu is a celebrity for a blink of an eye, flying into the night, spotlighted by porchlights and streetlamps, then vanishing before you can say Is that a moth or a beetle?

The huhu larva’s wood-boring activities help break down dead trees, contributing to nutrient cycling in New Zealand forests. It is also part of New Zealand’s natural heritage and has a place in traditional practices and stories.

The huhu beetle is a grand example of how New Zealand’s wildlife blends strength, spectacle, and a surprising palate, a longhorn with a soft spot for bathed-in-nightlight strolls and, in its larval form, a bona fide protein-packed forest snack.
