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.
Habitat: Gardens, waste ground and woodland clearings. Food: Nectar. The caterpillars feed on bedstraws, willowherbs and in gardens they feed on fuchsias, and gooseberry. Special features: Large Elephant hawk-moths are one of the most brightly coloured moths found in the UK. Here at UK Safari we often receive email messages from people saying they've seen a pink butterfly which usually turns out to be an Elephant Hawkmoth.
