** Attention Valued Customers,
In February 2012, we made a minor modification to our amphibious emergence trap. The supporting frames of re-modeled traps are much stronger structurally. The netting part of the new trap, however, is almost almost identical to the old model. Please note this change before making purchases.
One purpose of emergence traps is to estimate population densities of insects. The trapping techniques of many emergence traps, however, involve in frequent visits to remove insects trapped inside.
Our amphibious emergence trap is basically a floorless, closed tent plus a collecting head and a collecting bottle. It covers a ground surface area about 1 by 1 meters. Because the collecting system of this amphibious emergence trap adopts the design used in our SLAM traps (Sea, Land, and Air Malaise trap), it can be left unattended for a long time and the removal of caught insects is simple.
The amphibious emergence trap is easy to assemble and is highly portable. When using it as a soil emergence trap, simply place the trap over selected survey spot. About 110-cm tall, this trap provides enough height to cover small shrubs or potted plants. Use dirt to cover the flaps around the base of each side to keep inside all insects emerging from soil. Each trap has two large dome-shaped openings for easy access to the interior. In windy conditions, use tent pegs to stake down loops at the four corners.

One unique feature of our amphibious emergence trap is its ability to go aquatic. By connecting ordinary 2-L soda bottles (not included) and our special trap floating kit (sold separately), this trap can be transformed into a floating emergence trap for use in wetlands.

Assembly
Amphibious Emergence Trap on Land (soil emergence trap)
-
Remove collecting bottle from zipped pocket on top of amphibious emergence trap.
-
Assemble poles. Make sure segments are completely seated in metal joints.
-
Push ends of one pole into white pockets at diagonal corners of amphibious emergence trap. Careful: do not over bend pole.
-
Clip hooks around pole. Take care to maintain gentle curve in pole.
-
Repeat Steps 3-4 with second pole and black pockets.
-
Put collecting bottle back into zipped pocket on top of amphibious emergence trap.
-
Tie ribbons around neck and body of collecting bottle.
-
Zip up pocket to lock collecting bottle into position.
Amphibious Emergence Trap on Water (floating emergence trap)
-
Complete Steps 1-8.
-
Use built-in ribbons to tie one float connector of floating kit (sold separately) to each corner of trap. Make sure larger end faces down.
-
Remove pole ends from corner pockets.
-
Insert pole ends into hole in top of float connectors.
-
Assemble 3-segment poles of floating kit. Make sure segments are entirely seated in joints.
-
Insert one pole into adjacent corner pockets of trap to form one side of bottom frame.
-
Repeat Step 14 with remaining poles to complete all 4 sides. This bottom frame stabilizes trap in wind and waves.
-
Pour water into four soda bottles (not included). Screw bottles into bottom of float connectors. We suggest using 2-L bottles and filling them about 65% with water (1.3 liters). This will produce enough buoyancy and weight to help trap float steadily on fresh water. Even so, you should test on site to see how much water is actually needed.
NOTE Parts of trap floating kit do not float. They will sink if dropped in water.
