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.
Adult Lifespan. The vast majority of butterflies live only a week or two at the longest. However, two types of butterflies are exceptions to this rule: temperate species that have a winter-dormancy and some tropical species. Tropical butterflies of the genus Heliconius may live for six months. Additionally, butterflies of the family Ithominae, the genera Morpho and Battus each live for several months as well. In general, larger butterflies tend to live longer lives than smaller butterflies. The location of a butterflies and the time of year they hatch also influence their lifespans. Because temperatures, food availability and the presence of parasites vary across the range of many species, some areas may produce butterflies that live twice as long as others do. Monarch butterflies have many generations per year, and some generations have longer lifespans than others.
