Adults take pollen and/or nectar. (Possibly eat vegetative parts as well?) Food plants include Goldenrod (Solidago), Feverfew (Parthenium), Coneflower (Echinacea), and Rattlesnake Master (Eryngium yuccafolium).
Life Cycle
Mating occurs on flowers. Larvae are found in decaying wood, e.g., stumps, and have also been found in bromeliads.
T. delta was found to be one of the most common beetles in a study of flower-visiting insects in the Everglades National Park. It was found on 13 different plant species. One of the most amazing observations was of mass aggregations of Trigonopeltastes delta numbering in the thousands on the very large inflorescences of Sabal palm (Sabal palmetto).(3)
