Ladybug


It was so clear last Friday, and I enjoyed walking along Dakhadaeva Street breezing fresh air. The sun shined brightly, and it seemed everything around was full of joy. And crossing the street I looked down at the ground and noticed a little bug crushed by a car. It was a ladybug. I felt sorry and continuing my way I saw lots of lady-bugs: the majority of them were already dead being stepped on; the others were crawling on the ground being too weak to fly.
This scene of hundreds little bodies made me ask a biologist about the cause of it. I supposed the mission of these little creatures was over, I thought they had already laid their eggs at last. But alas, it wasn’t so. They were out from the place they spent a winter just cause it was time for it to their mind. The biologist’s hypothesis was that all these little living-things I saw on the street flied out from a single place.
Ladybugs gather in large quantity together (up to hundreds of specimens) to spend the winter and one day in spring all members of this ‘family’ fly to the open air. But do you know what the best time for lady-bugs is to lay their eggs here? What do they feed of? And what is their role in the nature?


If you are not sure you can answer these questions follow the link and read an article about them: nationalgeographic.com


Ladybugs are and have been for very many years a favourite insect of children. The insects had many regional names (now mostly disused) in English, such as the ladybird, lady-cows, may-bug, golden-knop, golden-bugs.
Lady-cows is similar to Russian name of this insect 'божья коровка', isn;t it?
The ladybug was immortalised in the still-popular children's nursery rhyme Ladybird, Ladybird:

Ladybird, ladybird, fly away home
                    Your house is on fire and your children are gone
 All except one, and that's Little Anne
        For she has crept under the warming pan.

And how do you like this funny sons?

Man and Nature


The whole time man is on this planet he changes the habitat to make his living here more comfortable. This animation is about his influence on the environment and a possible result of it.


It's a depressive movie, isn't it? Does it reflect the real state of things? Is mankind so mortal for living organisms and non-living things?
Do you agree with the thought of Canadian poet Bliss Carman (April 15, 1861 – June 8, 1929) "To our housebred sentiment, it seems a pathetic thing that every wild creature should die a violent death. But, after all, what better fate could befall it than to render its life up for the preservation of other life … One may say, without being misanthropic, that the greatest joy in nature is the absence of man"?
