Hi! I came home and noticed these dead bugs on my windowsill in my bedroom. There were about 50 or more dead on the sill. I live in an apartment and there were about 5 on the sill in the living room. They are all dead, I have never seen them before today (I even cleaned yesterday, which involved dusting the windowsill!) I am very confused and maintenance is out for the weekend. Can anyone identify what they are, why they are dead, why I have never seen one alive, and why there are so many? Thank you!!
