Flue slope. Question-I've seen this type of venting 3-4 times a month in older houses and never had anyone complain. The bottom metal flue is the 80% furnace with an uphill rise from it to the newly lined masonry chimney (stainless steel liner).
Monarch butterflies utilize different habitat in the warm months versus the cold months. In the spring, summer and early fall, they can be found wherever there are milkweeds. Monarchs lay their eggs on milkweeds and they're always searching for them in fields, meadows and parks.
A butterfly is a usually day-flying insect of the order Lepidoptera. They are grouped together in the suborder Rhopalocera. Butterflies are closely related to moths, from which they evolved. The life of butterflies is closely connected to flowering plants, which their larvae (caterpillars) feed on, and their adults feed and lay their eggs on. They have a long-lasting history of co-evolution with flowering plants.
