Thanks for your question.

The scientific name consists of two parts. The first part is always capitalized and is called the “genus”. The second part is not capitalized and is called the species. Both are either underlined or in italics.

The most common millipede in Minnesota is known as Narceus americanus. Here is a little bit of information about it:

The house centipede is known as Scutigera coleoptrata. Here is some information about it:

Thanks for the great question and for consulting us.

Thanks for those scientific names on the millipede and centipedes.The names for the centipedes fit what I've seen, but I'm hoping for another, more common millipede name. I've never seen the giant millipede, Narceus americanus, here in Minnesota, if that's the correct link and name. When I work in my garden, however, there are tons of the little millipedes you see in the photo I've attached. Do you know the scientific name for this little guy? 

Thanks for your response. It has caused me to consult some of my colleagues and do further research on your initial question.

As far as I have been able to determine, the most common name for millipedes is simply “millipede”.

Besides what I mentioned in my initial answer, other millipedes that have been reported from Minnesota that match the millipede in your picture are:

1). Oxidus gracilis (Greenhouse millipede). This has only been reported as being found in the SE corner of Minnesota. This would rule out Scott County. Nevertheless, see the following:

2). Various species of Spirobolus: These millipedes are generally cylindrical and can vary in color. They are often found in leaf litter and decaying wood. This appears to be a rather rare millipede in Minnesota. I could find out very little about it. However its appearance is somewhat similar to the millipede in your picture. See:

3). Various species of Julida: These are cylindrical millipedes that can be found in various habitats, including under stones and in leaf litter. It has been reported for various Minnesota counties but not for Scott. Adults are slightly over 1 inch long. It has a good resemblance to the one in your picture. See the following:

That’s about it. Nothing really conclusive but is the best that I can provide with the resources available to me.
