When an insect spends most of its life in total darkness, it doesn’t much matter what color it is. So, it comes as no surprise that so many species of bark and ambrosia beetles maintain the same brown hue as they slowly tunnel through wood and feed on a fungus that they carry with them into their trees. This similarity of appearance has been taken to an extreme in what has turned out to be a cryptic species complex. What was once referred to as the “tea shot hole borer” is actually four distinct species who all look almost exactly the same.

More challenging than birdwatching and not nearly as popular, insect-watching — noting and sharing exactly what one sees and where — is nevertheless on the rise.

Concern about dwindling native insect populations is one reason why. And new technology has made it easier to log insect sightings and become part of wide-reaching "citizen-scientist" projects.
