Myrmecophila tibicinis w/Euglossa viridissima these orchid bees look like little emeralds. They hover around like a humming birds and were very curious about me taking their picture! Coming right up to me to check me out. They come to my Myrmecophila tibicinis and scrape the petals of the flowers. I'm not really sure for what purpose [please watch the video it explains their unusual behavior ].
update7-18-2008 My friend Eric H. pointed out to me that these are actually orchid bees! Be sure to check out his orchid species photographs blog and plant world blog! Thanks Eric!
Euglossine bees, also called orchid bees, are the only group of corbiculate bees whose non-parasitic members do not all possess eusocial behavior. Most of the species are solitary, though a few are communal, or exhibit simple forms of eusociality. There are about 200 described species, distributed in five genera: Euglossa, Eulaema, Eufriesea, Exaerete and the monotypic Aglae, all exclusively occurring in South or Central America (though one species, Euglossa viridissima, has become established in the United States). The latter two genera are cleptoparasites in the nests of other orchid bees. All except Eulaema are characterized by brilliant metallic coloration, primarily green, gold, and blue. Females gather pollen and nectar as food from a variety of plants, and resins, mud and other materials for nest building. Some of the same food plants are also used by the males, which however leave the nest upon hatching and do not return.
Myrmecophila is a genus of plants belonging to the family Orchidaceae. Species in this genus are either ephiphytic or lithophytic in their growth habit. Their slightly scented flowers are produced on pole like growths that extend upwards from 1 to 4 meters high and take up to 4 months to develop. Several of the Schomburgkia species were transferred into the genus Myrmecophila by Robert Allen Rolfe in 1917.
The name Myrmecophila is a derivative of the word myrmecophile and refers to the symbiotic relationship with colonies of ants that are usually found living in the large, hollowed-out, banana-like pseudobulbs. An opening in the base of each pseudobulb serves as an entrance for the ants which harvest nectar from the peduncles and flowers and forage on other plants in the community. The ants associated with Myrmecophila tibicinis pack many of the pseudobulbs with debris that includes other dead ants, a variety of insects, pieces of plant material, seeds and sand. Myrmecophila tibicinis directly utilizes minerals of the organic debris ("garbage dumps") deposited by the ants inside the hollow pseudobulbs. Since the open-canopied trees of the tropics can often be nutrient poor habitats, a small input of nutrients from insects can have a significant effect on plant survival and growth rates. Myrmecophila tibicinis can grow quite well in the absence of ants, though it is quite rare to find an uninhabited plant. The species of ant responsible for forming colonies in Myrmecophila tibicinis are as follows: Brachymyrmex, Camponotus planatus, Camponotus abdominalis, Camponotus rectangularis, and Crematogaster brevispinosa, Monomorium ebenium, Paratrechina longicornis, Zacryptocerus maculatus, and Ectatomma tuberculatum.
The type species Myrmecophila tibicinis is distributed in the tropical areas from southern Mexico through most of Central America.
