Apheloria virginiensis milipede

orange & black milipede

Apheloria virginiensis  – a “large” millipede

This fellow was spotted on Camp Trail, Cook Forest State Park, in May of 2019. He’s a member of the Xystodesmidae, a family of millipedes which was named by O. F. Cook (no relation!) in 1895.

According to Wikipedia, this 2-inch-plus orange & black flat-backed millipede has been “reported to secrete cyanide compounds as a defense” – so don’t touch it! If you have touched it, make sure to wash your hands since “the toxic compounds it secretes are poisonous and can cause extreme irritation if rubbed in the eyes.”  And, don’t bite one.  

Otherwise, these insects are harmless, and beneficial.  They love damp forest floors strewn with rotting wood and host to mosses and fungi.  They eat these things, and are an important part of the forest life cycle. 

March in Cook Forest

Last year the Bureau of Forestry, with the CFC and interested landowners, treated a number of the streamside hemlocks to prevent infection by HWA (hemlock woolly adelgid).

This stretch of Tom’s Run is near Shelter #1, off Forest Road. The blow-down is from last year – there has been substantially less wind damage so far in 2019.
