Advertisement Up here in the Northwest corner of the map, I have been collecting what I beleave to be two different species of Centipedes. I have been stumped as to the names of these. If anyone has any suggestions as to what they are, and any books that might help, I sure would be greatful. The first one is yellowish orange, the legs are lighter colored. They seem to max out at around 4.5" to 5". These are VERY fast. The second one is more redish in color. Again, the legs are lighter. They run on the smaller size 1.5" to 2" long. I must apoligize for not having a camera to post pictures.. Thanks for any and all info.. :?
