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.
Butterflies and moths use specific host plants. The host plant is the plant or plants that specific species of butterflies or moths can eat. For example, Gulf Fritillary caterpillars eat only specific passionvine plants. Butterflies with a short proboscis cannot drink nectar from a flower with a deep throat and nectar at the base of the flower. Some butterflies seem attracted to specific flowers and/or colors. We list below some or all host plants used by each specific species and nectar plants which seem to especially delight these butterfly species.
