Honeybees (Apis mellifera) are as always steady visitors. |
 |
 |
 |
 |
 |
 |
 |
 |
And so are Ivy Bees (Colletes hederae). The life cycle of this species follows the cycle of the English Ivy. Female Ivy Bees only visit those ivy flowers. |
 |
 |
 |
 |
 |
| Therefore, they have to work hard as long as the flowers give pollen and nectar. |
 |
 |
 |
 |
Male Ivy Bees also gather pollen and nectar, but they happen to visit other plants. In such a case, they are more difficult to identify. Here, look at the heavier antennae. |
 |
 |
| Other Hymenopterae are also present, like those Bumblebees. |
 |
 |
 |
| Unlike Honeybees and Ivy Bees, Bumblebees have a strange behavior on ivy. They seem to be dull, sluggish, almost drunk. |
 |
Ivy flowers exhale a strong odor and the active principle of ivy, named hederin, is sometimes used in the human medicine. It seems to have a sedative effect on some insects. |
 |
 |
This calmant effect was so strong on this Carpenter Bee (Xylocopa sp.) that, after feeding on a flower, it could not fly away normally and had to stay a few moments on a Pelargonium to recover. |
 |
 |
 |
 |
Other insect families seem to also appreciate this strong nectar, like this Red Admiral (Vanessa atalanta) which lets the photograph come near it without flying away... |
 |
 |
Likewise for this Painted Lady (Vanessa cardui)... |
 |
 |
| This little Geometridae (Idaea seriata) seems to appreciate good catering, like bigger ones. |
 |
 |
 |
| Coming back to Aculeates, here is an European Hornet (Vespa crabro), which is rare on this ivy stand, but frequents each year another one in the Parc Monceau. |
 |
 |
And some common wasps (Vespula vulgaris), less numerous this year... |
 |
 |
 |
 |
| Ladybeetles never miss such a rendez-vous, like Adalia bipunctata, with a red form and a black form... |
 |
 |
After two spots, here are seven spots (Coccinella septempunctata). |
 |
 |
And now the Asian multicolor Ladybeetle (Harmonia axyridis), as dangerous for aphids as for other ladybeetles. |
 |
 |
 |
How could those fascinating ivy flowers leave flies insensible... |
 |
| Here comes an Eristalis sp., then Eristalis tenax, to be identified by two hair stripes on the eyes. |
 |
 |
 |
 |
 |
 |
 |
| And now a Myathropa florea takes the time to spend a penny. |
 |
Syrphus ribesii is always splendid and really elegant. |
 |
 |
 |
 |
 |
 |
 |
Let's finish with this Syritta pipiens, to be identified because of its popeye-like back thighs. |
 |
 |
This little walk would not be complete without two pictures from last year, showing how the ivy fruits mature and become those black berries, which blackbirds are fond of. |
