7105.      They appear outside my backyard, around my backyard door, on the brick wall of my house. After I step on them, a patch of red blood spread. First time seeing them after few days of rain, I have not seen them before. People mentioned seeing them lately around 10km away from my home. What are they? Are they harmful? Why they are red-blooded?

Number 7105. This is an aphid (Hemiptera/Sternorrhyncha: Aphididae). The red you noted came from the aphids’ tissues and is not blood. These strictly are plant feeders; some species can vector viral diseases of plants. Click here for more detailed information

Number 7099. This is a case-bearing caterpillar; it would not be responsible for any bites. Worst case scenario would be if it were a clothes moth caterpillar, so if any of your blankets/bedclothes contain wool or silk, you should examine them for any sign of chewing damage.

7097.      This spider has began making a web on the wall above our toilet. It is a small spider, roughly 7mm long. I am slightly concerned that if it is venomous, when it makes a larger web it could get in someone hair in the early morning/late night when they aren’t paying attention. My phone is telling me it is a false widow, but from what I can find they are larger with different looking pattern. Is this spider dangerous? Should I worry about it or leave it alone? Caledonia, Ontario. Canada

7089.        Good afternoon, I’m trying to identify what I belied to be pupa in my garage. They are approximately 3-5mm in length and resemble to size and shape of mouse droppings. However they are light brown and appear to have “stripes” or articulated joints. I usually find them in collections of 10-20 at a time. I’d like to identify them to determine if they are a problem and how to get rid of them. Thank you. Ontario

Number 7089. These are the empty pupal cases of a muscoid fly (the group that includes house flies and their relatives). When the larvae (maggots) of these flies finish feeding, they often will then leave their food source and crawl away in order to find a drier place to undergo pupation.
