I try to understand why these animals go into the house in autumn.

Great, thanks for your photo and the name was finally identify this insect, it will serve to interest children in the class because of our son in this same sect custody death of sparkling color and pollen remained perched on his abdomen.

I have the same type of insect that digs holes and tunnels in the branches of an apple tree death.

I just recognize an insect that wanders into my garden and I was a little surprised by its size and color. Now, here I am reassured! It's beautiful nature, there is always something new to discover! We marvel every day a little more!

Very well taken photo with beautiful colors. And I managed to get 1 name in this insect that I see in my garden.

Bravo I could recognize the stupid that is in my field.

Very nice photo showing the smart black insect in its natural environment in full flower pollination.

The creature is called Xylocopa Violacea. Size 20 to 26 mm. Looks like a drone, gloss black with purple reflections. Makes its nest in pieces of wood, sec. Same biology as the bee. This is what I've been able to find. The creature lacks a bit of net, but he had to at all costs him to do his portrait. Bravo

A beautiful image, crisp and well coloured, just dab the pieces of flowers in the bottom right.

The flower button is a little the edge of the frame, but the insect appears well with the soft colors that surround it, bravo.
