Question
Insect
Insect  
We live in York Region in Ontario, Canada. We have almost an infestation of these extremely tiny moss colored insects. this is the second year that we have had them in our home. (We live on a horse farm). they are everywhere. I am not sure if they fly.They are even to small to pick up and examine. When touched it curls up into a tiny ball so it actually almost looks like a mouse dropping. I photographed it beside my pinkie so that you have an idea how tiny it is.
Any information is greatly appreciated. thank you.

Answer
Dear Michael - This is a short-snouted/broad-nosed weevil (Coleoptera: Curculionidae; subfamily Entiminae). They typically feed on the edges of leaves, giving the leaves a characteristic 'notched' appearance; their larvae primarily are root feeders, and some, like the strawberry root weevil and the black vine weevil, can be serious pests. However, the vast majority (likely including yours) do not appear to be of any economic importance; here is one example - http://tinyurl.com/ooyz4ct

Expertise

Will accept most questions in general entomology, including those related to medical entomology, taxonomy, ecology, arthropod surveillance, and pest management. If you are requesting a 'mystery bug' identification, PLEASE either attach an image to your question, or post an image on a web page (such as Flickr) so that I can look at it, as verbal descriptions frequently are insufficient for a definitive identification.

Experience

21 years in the U.S. Army as a medical entomologist; duties varied from surveillance of pest populations (including mosquitoes, cockroaches, ticks, and stored products pests) to conducting research on mosquito-virus ecological relationships and mosquito faunal studies. Ten years as a civilian analyst for the Department of Defense, primarily on distribution of vector-borne diseases worldwide. Limited experience on surveillance of agricultural insects in North Dakota and Indiana.
