A dozen monarchs, neatly packaged in an insulated FedEx box, will make a 1,600-mile overnight journey from Appleton International Airport in Greenville, Wisconsin to a home in Mission, Texas, to catch up with fellow monarchs already in South Texas on their migration to Mexico. The shipping cost $130 and was paid by Friends of Butterfly Gardens Inc. Jack Voight, president of the nonprofit organization, said $130 is a small cost to save 12 monarchs, which otherwise would be in peril on their flight to Mexico at this time of year due to a lack of nectar along the way and the potential for freezing temperatures. "If we can save 12 monarchs, and half the monarchs are females, each one will lay 400 eggs next spring," Voight told The Post-Crescent, part of the USA TODAY Network. "So we're going to increase the population. The population has gone down by 80 to 90%." Visit the link in bio to read more about the monarchs' journey.
