Re: Hybrids


Excellent observation on the VERY specific tastes of many insects! Now, if
you really want to get into esoteric baits, talk to the tropical butterfly

While wandering around my garden this morning with a cup of coffee I was
tickled to see "mass" aggregations of male Eulaema sp. (cingulata?) on four
or five receptive Anthurium huixtlense spadices (three mature plants). This
was really quite impressive - literally standing room only for many dozens
of these bumble-bee sized velvet black euglossines with shiny gold abdomens.
Curiously, I also have a number of A. armeniense and A. chiapasense that are
also in various stages of flowering right now, and they do not appear to
attract these bees but rather, a sorta nondescript Trigona species.

BTW - I have, on many occasions during the rainy season, observed some type
of nocturnal, "haemophagus-looking" dipteran clearly attracted to the nectar
secreted by my Anthurium andreanum 'Kansako' plants. They appear to be very
engrossed in tubing up nectar when I have put a light on them.

Anyhoots - neat stuff - I suppose this is one of many reasons to grow
tropical plants in the tropics.

Cheerio - Jay
