ladybug haven

Three pumpkin bettles and one lady bug.

The ladybugs love the zucchini. I was gently throwing them over the fence (ha ha like they are not going to fly straight back over) because someone told me once they did a lot of damage to plants. Mum said they were good to have in the garden so I looked it up.
Answer. The lady bugs live nearly completly on Aphids which are the badies in the garden. So the lady bugs are good for the garden. There is quite a large colony on my zucchini plants and as you can see they are multiplying at a great rate. So I will leave them be but I do wonder what they eat if there are no aphids. Or are there aphids on my zucchini and I just don't know it.
P.S.
In my happiness at finding a colony of good bugs in my garden I assumed that the other lady bug type bugs with the elongated bodies where juvenile lady bugs but I was terribly mistaken.   They are in fact pumpkin bugs and they are the badies of the garden.  Tonight was the first time that I had seen the pumpkin bug so hopefully I can erradicate them before they become a problem.

I am now on 'mission pumpkin beetle' and the last man standing wins.
