It was cool and partly sunny as our May Day survey was completed by three volunteers. The forked orange projection giving the caterpillar below a "longhorn look" is called an osmeterium. All swallowtail larvae possess this organ, which is normally hidden. It emits a pungent odor and is everted when the insect feels threatened.
