Hello! I recently purchased some 3rd cutting alfalfa hay from Madrid Iowa. After unloading the hay I noticed small, Poppy seed sized insects crawling in the hay in masses. They are black to brown in color. I reached out to the individual I purchased the hay from to see if they knew what they were and did not receive a response. I was hoping you could assist with identification of the insects and let me know if they present any concerns to our horses that will be eating the hay or infestation to our barn/property. Thank you, Stephanie
