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.
Butterfly habitats must be protected to ensure the survival of their species. Those who want to attract butterflies into their gardens should first find out which species are found in your area. Then find out their host plant and grow them in your garden or provide them with food they like.
