Consistent with that hypothesis, laboratory experiments revealed: (a) starved
larvae varied in their tendency to disperse from paper leaf models; (b) starved
larvae readily silked only during their first day; (c) larvae became increasingly
sedentary the longer they were exposed to plant foliage; (d) when provided with
severalopportunities to silk, larvae became sedentary after exposure to arborvitae
foliage, but repeatedly silked after exposure to maple (Acer species) foliage or
paper; and (e) larvae were less inclined to silk from foliage of arborvitae than from
maple
