Efeu-Seidenbiene / Ivy Bee
Merkmale / Morphologic features:
Was ist zu sehen: Teilausschnitt des Kopfes. Feinstruktur der Kutikula. Gefiederte Haare, charakteristisch für alle Bienen. Die haare sind jedoch in großer Vielfalt bei unterschiedlichen Arten ausgeprägt. Unterer Bildrand: Basis der Fühler. Darüber am oberen Bildrand (in Richtung Hinterleib) drei Ozellen auf dem Kopf. Zwischen Fühlern und mittlerer Ozelle verläuft ein Scheitelkamm. Dieser ist bei einigen Bienenarten ein gutes Art-Kennmerkmal.

What we can see here: Details from the head. Fine structure of the cuticle. Feathery hairs typical of all bees but developed in all sorts of shade. Lower rim of photo: base of antennae. Above at the upper rim of photo (in direction towards the abdomen) three ocelli. Between the antennae, there is a crest. In some bee species this is indicative for species determination.
Funddatum /Collection Date:
17.09.2019: - colony showing full flight activity.
09.10.2019: Latest two females found crawling at nesting site during rain shower. Entrance holes were still visible but partially obscured, possibly by weather erosion.
25.10.2019: even though weather was sunny, and the slope of the nesting site was fully sun exposed, no bee was seen. Neither, any of the entrance holes could be identified.
21.09.2020 A sunny, warm day, but no evidence of a thriving colony, no evidence of a single bee at the nesting site! No nest entrances. A dead pine tree had shed bark onto the nesting site. But that bark was removed about a month previous to bee-hatching time. At the Schauenburg-Ivy bush two females and one male were observed on 21st Sept. 2020. One female possessed two parasitic larvae (triungulins) of the species Stenoria analis . Was the colony killed by these parasites or was it the storm-shed bark on the nests keeping the ground to moist? Or was it a nearby hornets nest....?

Bemerkungen / Notices:
Beobachtet auf Hedera helix Paarung in einer nahbeigelegenen Nist-Kolonie am 17.09.2019 beobachtet. Die zahlreichen Ausgänge der Kolonie wurden von mir im November 2018 entdeckt. Jedoch flogen zu dieser Zeit keine Bienen. / Mating observed in nearby nesting-colony observed on Sept. 17. 2019. The nest opening were discovered in November 2018 but no bees were seen then.
The species is one of three sibling species with:
Colletes halophilus Verhoeff, 1944;
Colletes succinctus Linnaeus, 1758
