What's Nesting in the Bird House???

What’s Nesting in the Bird House???

Dear Toni,
We are presuming that you attached two images of a bird house because the creature in question has nested inside the bird house.  Your letter did not describe the creature, which you have stated is a Bee.  The Orchid Bee,
Euglossa dilemma, is a bright green bee that is often seen hovering near blossoms.  If the Bee you have had for over a year is not bright green, it is not the Orchid Bee.  We have received another report of Green Orchid Bees nesting in an abandoned birdhouse, but Bumble Bees will also nest in a birdhouse.  Only the female Orchid Bee builds the nest, so you should use the pronoun “she” when referring to your creature.

Hi Stacey,
This is an Orchid Bee,
Euglossa dilemma.  It is a neotropical species and we first became aware of the Orchid Bee‘s presence in Florida in 2004.  Since that time, it has become well established.

This bee has a strange ”backpack” on it’s back and , in addition to a ”normal” bee tongue-tube, it appears to lower and extend it’s lower mandible and some pinkish ”baleen” comes out. What is this bee and what is the story with these two strange characteristics?

Dear Linda,
Thank you for sending us your wonderful photographs of this unusual Bee.

We believe that it looks identical to an Orchid Bee, Eulaema cingulata, that we posted some years back.  Karl assisted us in that identification and he provided us some links.  We believe the “backpack” you observed is an orchid pollen pack or pollinarium.  Karl wrote:  “Apparently male Euglossine bees are attracted to certain orchids not to gather nectar, which these orchids don’t possess, but rather to collect fragrant compounds which are then used to attract female bees. The male flowers are designed so that the pollinarium is flung onto the bee when it lands, where it sticks until the bee visits a female flower where it completes the pollination. Both males and females visit other flowers to obtain the nectar they need.”  Karl also provided us with a link to this photo of an Orchid Bee with a pollinarium that looks like your documentation.  Here is a photo of a mounted specimen with a pollinarium from Spiegel Online, but alas, we don’t read German.  The Biodiversity of Belize website has a similar photograph and you must scroll to the bottom of the page.  There the site offers the information about Eulaema cingulata:  “Males of this and related species pollinate a number of Neotropical orchids such as this Catasetum. These male bees visit the flowers nut so much as for the nectar but in order to obtain certain chemicals they need. For this reason the males can also be attracted by using benzyl acetate and other chemical substances as bait.  The bee to the right is incapacitated by a pollinarium of Catasetum integerrimum that is stuck to its wing. It was unable to remove this pollinarium and only after I removed it myself, the bee was able to fly again.”  The interconnectivity of all things on this planet includes such highly specialized adaptations as the pollination of a specific orchid by a specific Orchid Bee.

Julian Donahue provides some information.
I think the word is “pollinium,” plural “pollinia,” at least that’s the way I’ve always seen it.
Milkweeds have a similar pollination apparatus, with pollen “clips” that I’ve seen attached to the legs and other parts of various moths.
Julian

Ed. Note:
Encyclopedia Britannica online provides this definition for pollinarium:  “…the caudicles, which are derived from the anther. Orchids that have a stipe also have caudicles that connect the pollinia to the apex of the stipe. The pollinia, stipe, and viscidium are called the pollinarium.”  Encyclopedia Britannica online provides this definition for pollinium:  “The pollen grains are usually bound together by threads of a clear, sticky substance (viscin) in masses called pollinia. Two basic kinds of pollinia exist: one has soft, mealy packets bound together to a viscin core by viscin threads and is called sectile; the other kind ranges from soft, mealy pollinia, through more compact masses, to hard, waxlike pollinia; the latter usually have some mealy…”  So, when other parts of the plant (orchid) are included with the pollen, pollinarium is more correct.  Guess we need an orchid expert to determine which word is more correct in this situation. 

Daniel and Karl,
Thank you so much for your assistance. You have a wonderful resource for those of us who like to know what is around us. I have been photographing and documenting what we find in our property here in Panama and so many of the insects are new to me. I have an interesting praying mantis with purple spots that I will send next time. Thank you.

There are pictures of an orchid bee with a strange appendage on it’s back. I may know what that is. There is a certain orchid in Costa Rica that blooms in the lowland broad leaf deciduous forest which is a member of the lady slipper orchids. When the flower is ripe and opens it has a spring mechanism within it that when triggered by the orchid bee it shoots a small miniature plant like thing (see orchid bee picture and appendage stuck to it’ back) that has some sort of latex glue on it. I actually think it’s a miniature plant, that the bee gets to transport on it’s back to a new location thus not only pollinating the plant but taking it’s offspring to a new location. This is a theory.

Thanks Daniel,
We recently posted photos of an Orchid Bee with the Pollinarium of an orchid on its back.

Photographed this bug in my south Florida back yard. It was really attracted to my basil plant. Is it a bee or a Fly?

Green Orchid Bee

Hi Laura,
We first reported on Green Orchid Bees,
Euglossa dilemma, in Florida in 2004, and that posting created quite a stir.  We have since learned that this Central American species has become well established in southern Florida.

Hello Bugman!
I rescued this fly from my pool yesterday & have been trying to find out what it is… As you can see it’s very shiny green & where the ”mouth” is, it has pretty big silver pincers.
Can you help? ;-)
Thanks!

Orchid Bee

Hi PunkRockGirl,
We are going to also address a separate email you sent regarding using our search engine.  Type in a few key words.  We tried that with this request.  Knowing the insect order really helps, but when we first saw a photo of this creature in flight, we were uncertain if it was a bee or a fly.  We typed in “Metallic Green Fly” into our What’s That Bug? search engine and one of the choices was this Orchid Bee posting from 2004 when we first reported on this Central American species being sighted in Florida.  They are now firmly established in Florida.  The Orchid Bee is a beautiful creature and we now have many postings in our archive.  You can compare the face to this image from BugGuide and BugGuide also has other information.

I see these bugs on rare occassions. They will hover in one spot in mid air. If you disturb them, they fly away and then they will return to the exact same spot. They move very quickly.
These photos were taken in South Florida in June.

Green Orchid Bee

Dear Danman,
When we first posted an image of a Green Orchid Bee in the genus
Euglossa, in 2004, it was something of a sensation because it was a more tropical species that was not reported from Florida.  It has since become quite well established.  Its presence could be due to global warming or other man made causes like accidental introduction or cultivation of its food source in gardens.

Daniel,
I first saw these in Hollywood, Florida in 1987. That is 18 years previous to your 2004 post. They would find a spot in mid air for no apparent reason and they would hover without any deviation. If you waved your hand, they would fly away in an arc, and the they would return to that same spot in mid air. They are raelly odd insects.
Danman

Wow, that is fascinating.  We wonder how they avoided detection for so long.  See this:  Establishment of the neotropical Orchid Bee Euglossa viridissima (Hymenoptera:  Apidae) in Florida which states  “During the summer of 2003, however, several male Euglossa viridissima Friese 1899 were trapped around Fort Lauderdale (26°08’N, 80°08’W), Florida, by USDA employees in the fruit fly monitoring program and sent to the Florida State Collection of Arthropods for identification (Wiley 2004).”  To the best of our knowledge, that represents the first official Florida sighting.
