Steps in spreading a butterfly. r6 I{OUNTING AND PRDSERVING INSECTS The timc required for a spread specimen to dry will vary with its size ancl with temperature and humidity. A largc butterfly or moth that might take several days to dry at normal room conditions can be driecl in an hour or two with heat-in an oven or undcr an electric light. To determine if the specimen is dry, touch thc abdomen gently rvith a pin;if the body is still the specimen is dry, but iI the abdomen is still flexible the specimen is not yet dry. A specimen spread on a spreading boarcl is spread the same way, exccpt that the insect is pinDed through the thorax from above and placed at the standard height on the pin. 'Ihe pinncd specimen is then placed on the board, the pin going into (perhaps through) the cork strip at the bottom oi the groove, until the basc of the wings is even vith the uppcr surlace of the top piece of the board. Next the wings are spread and fastcned dorvn and the antennae o ented to a symmetrical position- Do not removc the pin in the insect's body alter the spreading. Mounting on Slides.
