Extremely small (21 cm diameter by 5 cm thick) after folded and lightweight (280 grams), our pop-up butterfly bait trap easily fits into backpacks for field trips.
The trap is held open by foldable rings (38 cm diameter) at top and bottom of the black cylinder. Of 96 x 26 mesh polyester netting, this pop-up butterfly bait trap is equipped with a 2-way, full-length (about 90 cm) zippered side opening convenient for removing captured butterflies from either top-down or bottom-up. There is no cone or lip at bottom to stop butterflies from escaping.
The removable bait tray (20 cm in diameter, included) hangs by plastic hooks from three drawstrings beneath the cylinder. To hook tray to cylinder, pass the hook through the hole in the tray so the open part of the hook is outside the tray.
There is an 8 cm long "skirt" sewn to the bottom. You can either fold up this skirt or use the cord lock attached to each drawstring to adjust the gap between bait tray and bottom entrance.
For a larger landing platform, simply attach cardboard or hard plastic sheeting (not provided) to bottom of the tray.
