Endangered Giant Air Plant (tillandsia utriculata)
killed by invasive, Mexican weevil (metamasius callizona).
Weevil lays eggs in mature bromeliad and the larvae kill the plant before it can reproduce. This plant, 15-20 years old, had 5 larvae in various stages of maturity.

Sarasota County and Selby Gardens has hosted several workshops on bromeliads threatened by the Mexican weevil. The conference was attended by staff members, researchers and volunteers from several agencies and natural lands--including Florida State parks, the University of Florida, New College, Sarasota County, Selby and Naples Botanical Gardens and volunteers--to learn about and discuss strategies to save several threatened species of bromeliad, especially tillandsia utriculata, Giant Air Plant, GAP, (pictured at left with emerging bloom spike)
