Butterfly Traps

About Our Traps

Bait traps are used to capture Lepidoptera attracted to fermenting fruit, faeces, and rotting meat. Our traps are based on the tried and tested Van Someren-Rydon style and take into account scientific research on effective trap design. They are lightweight and pack down to a slim size, and have a number of features designed to improve performance and ease of use.

A 36cm (14") landing platform made of easy to clean semi-rigid pvc is used for our traps. The support cords attaching the main trap cylinder to the landing platform can be easily adjusted from 2cm (3/4") to up to 13cm (5") using sliding cord-locks, so you don't have to struggle with strings and knots.

The main netting cylinder is fully washable and is sewn with no internal projecting seams. Four hanging points provide secure positioning. The cylinder is fitted with a full length vertical entry double-slider side zip, for easy access to the butterflies at any point, and for the removal of unwanted insects.

Finally, to trap lower-flying species or where there is no available hanging point, our 'hang-it' frame may be used. Made of fibreglass rods, this frame is quick and easy to assemble. A removable clear colourless PVC cover which protects the top section of the trap from rain is also available.

Johnson butterfly trap - regular

The regular length Johnson trap is 75cm (30") long. It is hyperboloid in shape with a top ring of 40cm (16"), and lower ring of 30cm (12") below which extends a short skirt with drawstring. The main body of the trap is black nylon, which makes the trap less conspicuous, with a white lid to encourage upward flight. There is a full length double-slider zip for easy photography, removal, or release of specimens. The 35cm (14") wide landing platform is attached with cord-locks and fully adjustable strings which run down the inside of the trap from the lower ring, thereby holding out the skirt. Four tape-loop hanging points are provided for stability. The whole trap, including platform, weighs less than 500g (17oz).

Aperture and Cone
This skirted system allows the lower part of the trap to be easily raised to change the bait without disturbing the top section of the trap. It is also possible to slightly narrow the aperture by closing the skirt somewhat (note however that excessive narrowing will destabilise the platform and is therefore not recommended), or alternatively an optional detachable cone is available which does the same job.

Observation Cage
If required, the landing platform can be quickly and easily removed, and the skirt closed completely, leaving a hanging study cage. Or alternatively, optional support rods can be attached, the skirt closed, and the cage taken down and inverted to give a temporary freestanding observation cage. When used in this way, a lightweight feeder can be hung inside by attaching a tape between the support loops.

Bait Recipe

A Simple Bait Recipe to Attract Butterflies:
2-3 very over-ripe bananas (or other over-ripe fruit to a similar quantity)
3.5oz (100g) white sugar
1/2 can of beer
1/2 crushed brewer's yeast tablet (optional)
Warm water
2 pint container with lid

Mash or coarsely blend the fruit with the sugar, and pour into the 2 pint container. Add the beer (and yeast if using), and enough additional water to make up to the 2 pint quantity. Mix well. Place the lid loosely on the jar - it should begin to ferment, so do not place on too tightly or the container may explode!

The bait is now finished. It can be used straight away, or kept at room temperature and stored for a few weeks. To use, pour a small amount into a plant saucer or shallow bowl (with or without a small amount of chopped additional over-ripe fruit) and place where you wish.
