COVER Cycad plants use thermogenesis to warm their reproductive
cones. A beetle dusted with pollen and fluorescent dyes lands on the
warm cone of a cycad. High concentrations of dye have been deposited on
the cone’s hottest regions during previous visits by other labeled
beetles. Beetle pollinators use these thermal infrared patterns as a
guide to locate host pollen and ovulate cones.
