Flycatcher birds that migrate from Africa to Europe feed their nestlings mostly with moth caterpillars. The data presented show the mean dates of egg laying, hatching, and fledging of flycatcher young, and the 1980 and 2000 peak mass of caterpillars.

Why are ecologists  concerned about the shift in  date from May 28 in  1980 to May 15 in  2000 of the caterpillar peak mass?
