This is not Pearl Harbor, Hawaii, on the morning of December 7, 1941, but rather College Station, Texas, on the morning of October 15, 2014. The incoming waves are not Japanese warplanes but Monarch butterflies. The colors are not those of the Rising Sun — red and white — but the unmistakable orange, black and white markings that set the Monarch apart as our most recognizable and beloved butterfly and the Texas state insect.

Looking east, they appear as if by magic out of the risen sun. ‘Poof’ — one appears. ‘Poof’ — another — and ‘poof’ — another! As you scan the horizon one moment, the sky is empty until, seemingly out of nowhere in the next magical moment, ‘poof’ — the next wave announces its arrival. It is more of a ripple than a wave, as they appear in ones or twos. But the tide is building, and one has hopes for a butterfly tsunami.

Am I being too optimistic? The sad stories of the precipitous decline in the number of Monarchs has seen pessimism take hold, and it is hard to shake. Yet here, borne upon morning’s first rays, is a glimmer of hope. The sun shimmers off the diaphanous wings, their colors enhanced by the combination of sunlight passing through them and the reflective, refractive capacity of wing scales that serve to protect them like the roof shingles they resemble.

They float up and over the USDA People’s Garden as if drawn by some Svengali. However, one should not associate the Monarchs with evil. The indigenous peoples of the Monarchs’ homeland in the state of Michoacan, Mexico, have, since time immemorial, considered the returning butterflies to be the souls of their deceased relatives returning to Earth. The butterflies’ arrival coincides with the Dia de los Muertos (Day of the Dead). They are honored with feasts, celebrations and elaborate ofrendas (offerings). It is a time of celebration, and it feels like that today at the USDA office, where even many of those working diligently inside are drawn outside to be a part of this spectacle.

Scientists know that the Monarchs are following a time-honored path. But what are the triggers for one of the world’s greatest and longest insect migrations? To help contribute to that research, I net six Monarchs and donate them to a research lab on the Texas A&M campus, where they will be used to improve the genetic diversity of the live lab colony of Monarchs. I have fellow observers tag and release several more as part of a citizen scientist project to learn more of the migration routes and timetable.

I lose count of the number flying by. I am up to 150, but there were many more that I missed. I only saw a total of 12 last spring when the grandparents of these butterflies had passed through Texas en route to their breeding grounds in the Midwest and Canada, where conditions this year appear to have favored good reproduction rates despite loss of habitat and reduced acreage of milkweed plants that nourish their caterpillar progeny.

Anecdotal reports of these increases had reached me and then, in a rare coincidence, a giant swarm of migrating Monarchs resembling a giant butterfly showed up on radar for a short time on the afternoon of Friday, September 19, 2014. The suspicion was that these were hundreds of Monarchs flying at between 5,000 and 6,000 feet, heading south over Southern Illinois and Central Missouri, the radar signals suggesting that the ‘targets’ were flapping, flat and biological. It is entirely plausible that the Monarchs we see today were part of that swarm.

I watch as some of my transient friends settle on a false willow to rest, feed and recharge with nectar alongside a myriad of honey bees. All seems right with the world. The Monarchs have uplifted our souls.
