Presumed insect eggs

Asked November 5, 2020, 1:28 AM EST

Appearing around mid-october, the house and other wooden surfaces have lots of what seemed to be eggs on them. They are about .5 to .75 inch long, shaped like a short darning needle, attached on one end and standing straight up/away from the surface. They are light in color Can you help me identify this friend or foe???

Hi, Yes these are an insect and are quite unique and are called case bearing moths, there are several types of species. There is no way to positively ID which species from photos alone.The larvae build the cases, which offer protection and camouflage in some cases. These are most likely a weed feeding species, there is one that can be found on Russian Thistle, a common weed in our area, another that can be found on larches. They are not harmful, and they will emerge as moths in the spring.
