Proturans are hexapods that are very rarely seen or looked for, but they are part of the insect food web.
The microscopic Proturans are 6-legged creatures that live in soil. They are shorter than a typed-out exclamation mark! Hundreds of them can live in a cup of good earth in the woods, in crop fields and in backyards. They are virtually blind and sense their surroundings by touch and taste. They scrape off bits of fungi and plant roots into their small mouths. Some species breathe through their exoskeletons, others have a trachea (windpipe). Larvae are even smaller than adults and grow a few segments as they mature.
As you can imagine, photos of them are difficult to take as they require intense magnification (via microscope) in order to see any detail in their physiology.
Scientific Name: Acerentomon sp.
Size (Adult; Length): 1mm to 2mm (0.04in to 0.08in)
Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
