It's a story about Darwin meeting a time traveler who tries to convince him that his future publications will change the world.
The time traveler presents a moth to Darwin as a gift. Here's a a little background on its significance:
In 1862 Darwin predicted that the unusually long spur of the Madagascar orchid (Angraecum sesquipedale) meant that there must exist a moth with a proboscis long enough to reach the nectar and ensure pollination of the flower. Such a moth (Xanthopan morganii praedicta or Wallace's sphinx moth) was discovered in 1903, but it wasn't confirmed until 1997 that Wallace's sphinx moth is indeed the pollinator of Darwin's orchid.
