According to National Geographic News, “entomologists may have caught evolution in the act”.1 They have reportedly found a “previously undocumented population of vampire moths” in far-eastern Russia. The moths look just like a fruit-eating moth species, Calyptra thalictri, which lives in central and southern Europe.2 But the Russian population of moths sucks blood! Entomologists say it looks like the bloodsucking moths have evolved from purely fruit-eating ones.
Film footage1 shows researchers offering their hands to the moths, which the moths accepted, drilling their hook-and-barb-lined tongues under the skin. One researcher can be heard saying “It’s starting to hurt” as a moth began sucking her blood. The blood-sucking can go on for several minutes—in fact, the researchers reported that some moths sucked for more than 20 minutes!
Entomologists say that this discovery suggests that the Russian population of moths “could be on an ‘evolutionary trajectory’ away from other Calyptra thalictri populations”.1
However, contrary to the researchers’ claim, this is most certainly not “evolution at work”.1 Behaviour modification is not evolution! The moths are still moths. The “vampire moth” is more aptly viewed as yet another example of how a creature that is normally herbivorous can turn to non-plant food sources when it suits, as has happened with many creatures since the Fall.3–8 Conversely, creatures that today are thought of as ‘carnivores’ can be herbivorous—a readily understandable legacy of an originally perfect world in which all creatures were plant-eaters (Genesis 1:30).9–12
