Abstract
The adhesive strength of specialized setae on the palettes of male Dytiscus alaskanus was investigated by recording the mass that palettes were able to lift. Large primary and secondary adhesive setae were removed and the adhesive strength of the palette was tested. The primary and secondary adhesive setae accounted for 59.5% of the adhesive strength of the palette. The ability of the palette to hold nearly 4 times the mass of a female may be needed to overcome the force generated by an accelerating female.
