They are called “worms,” “wireworms,” “armyworms” and names that are not repeatable, but the pest is always the same -- millipedes. And usually not one millipede, but hoards, hundreds, thousands or millions of millipedes.
When (and if) Iowans think about centipedes they probably picture the house centipede. This common home and garden resident is up to 1.5 inches long and has 15 pairs of very long, slender legs stretched proudly to the sides of the body. Each of the 30, fragile-looking legs is almost equal to the length of the body and is encircled by dark and white bands. The body is brown to grayish-yellow with three dark stripes.
There are both wingless and winged forms, according to Matt O’Neal, assistant professor, Entomology. He says wingless soybean aphid adults are about 1⁄16 inch in length, pale yellow or green, and have dark-tipped cornicles (tail pipes) near the end of the abdomen. The winged form has a shiny black head and thorax with a dark green abdomen and black cornicles.
