What is this larvae

Asked June 4, 2016, 11:18 AM EDT

What is this? These larvae are swarming all over the roots of my perennial plant roots. They range from 1\8 - 1\2 inches long. My primrose are not flowering the way they should be. They are in the mulch and spreading. The tiny ones are almost white/cream in color and the larger they get they are more grey/brown. If disturbed they curl into a fetal position. See attached photo. There are 3 in the picture.

The insect is a sowbug http://www.extension.umn.edu/garden/insects/find/sowbugs-millipedes-centipedes/ They are found in moist, damp areas. They are not the reason your plant is not blooming. They eat decaying plant matter. It is possible the area is too wet for your plant.
