Granada, march 2008, 1400 m.  There were many females planting eggs in the soil, in fly with abrupt movements, but I can't see any bee holes also, what is this thing they have in the back? the sand for the eggs? thanks! Edited by javig on 26-03-2008 19:58 |

i see no photos as far as i know Bombylius do not 'plant' their eggs but flick them towards potential bee-holes while in flight. what you have probably observed is females collecting dust with which they coat their eggs before flicking them. |

I saw the photos yesterday - for some reason they don't load today. They show females hovering over bare soil. Very good pics, especially considering how difficult it is to shoot flying insects in the field.

May be Bombylius discolor? |

OK i see now, yes they are egg flicking, the first picture shows the dust chamber everted as it is when picking up dust from the ground. not sure why it should be everted during egg laying, perhaps you have caught the process of discharging an egg which is too quick to see normally. i agree that they are B. discolor. |
