Mosquitoes which are required for identification should never be touched
with the fingers. A pin or needle should be used for moving them when
this is necessary. A card-disc should be taken, and one of the No. 20 silver
pins thrust through its centre, so that about half the pin projects each side.
The mosquito to be mounted is turned over on to its back, and the point of
the pin carrying the disc is entered into its thorax at the point of origin of
the legs, and made to emerge through the dorsum of the thorax. On turn-
ing the disc over, the mosquito will be found to be mounted in its natural
position, right side uppermost, and its legs and wings can be gently arranged
on the card-disc with the aid of a pin. An ordinary pin is now thrust
through the edge of the card-disc to attach it to the cork in the bottom of
the box. (See figure.)
