Trombidium is a genus of small parasitic arachnids known as red velvet mites. It is very widespread, occurring on every continent except Antarctica. It is most common in northern Europe and in North America. In the United States it is common east of the Great Plains and west of the Rocky Mountains, scattered and uncommon between. It is common in Minnesota. There are at least 35 living and 1 fossilized Trombidium species worldwide, and at least three species in North America north of Mexico.

Adults are found in moist woods on vegetation, in forest litter, and on soil. They feed on other mites, primitive wingless insects, and eggs of insects and snails. Larvae are parasitic on insects, spiders, harvestmen, and scorpions. Some species live for several years, while other species live for just one year. The female scatters eggs on the surface of the soil. When the eggs hatch, the larvae search for a host to feed on.

 
           
 
Description
 
 

Red velvet mites are small arachnids but large mites. Adults are (3 mm to 4 mm) in length and oval to more or less rounded rectangular in shape. They are bright red and and densely covered with short, velvety hairs. This is the feature that gives the genus its common name. Adults have four pairs of legs. Juveniles have just three pairs.

About

Published on Oct 21, 2015

Though these little critters may be more abundant than we realise, their minuscule size makes them almost impossible to see among the undergrowth & leaf litter of the forest. Unless of course, as in this rare occasion, they're out in force & hunting for their prey. On this particular walk we spotted no less than 30 to 35 of them in a relatively small area. So, there's no surprise that I had to take every opportunity I had & film & photograph as many as I could. To see a detailed collection of the photographs, head to my Facebook page www.facebook.com/underamushroom
