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