| Colletes cunicularius |
|
|
Amstelveen, 1 April 2009. I first saw a few females of this species in 2008. This spring they were much more numerous, and both males and females were present - as shown by this copulating pair. |
| Sphecodes albilabris | |
|
|
|
Amstelveen, 1 April 2009. This species is a cuckoo-bee of Colletes cunicularius above. What amazes me is that one year after I first saw C. cunicularius here, several females of its cuckoo-bee were already present. This suggests that last years brood was already parasitized; which in turn suggests that both species arrived almost simultaneously. Since the source population may well be 20 km away, I find this surprising. |
