Nepenthes Nectar Attracts Crawling Insects, Not Flying Ones—And Skip the Humidity Dome

Steven's N. ventrata produces nectar but ignores flying insects (they go to the light bulb). He plans to buy N. ramispina and asks about humidity adaptation using a paper bag.

Nepenthes Target Crawlers

Jacob Farin: "Nepenthes generally attract crawling insects, such as ants. They'll capture a few flying insects, but keep in mind that insects will get attracted to the nectar when they're ready to feed. Otherwise, they'll be attracted to bright shiny things, such as a light bulb."

No Humidity Dome Needed

"I don't recommend using any humidity dome for Nepenthes. … Nepenthes ramispina is a very close relative to Nepenthes sanguinea. Both plants grow in the same location in Malaysia and acclimate to lower humidity just fine."

Jeff grows both to adult size in a west window without terrarium or dome; summer humidity drops below 20%. Keep soil moist, provide strong light, and they'll adapt.

Upcoming DVD

A "Grow Nepenthes as Houseplants" DVD was nearing release (November).
