Symmetry of bark beetle tracks on the bark

One friend showed a piece of bark with a strange pattern, the lines of the moves coincide with the field strength lines of an imaginary magnet . Is this normal? Approximately as in the drawing.

normal. the female makes the main passage and lays eggs in its walls every few mm. Larvae from the eggs can drill the bark only from the mother's stroke. Gradually, someone lags behind or dies, and the larvae themselves become larger, so the moves are not very parallel. Plus, they bypass bitches.

So why aren't they just like the sun?usually there are some zigzags.

This man, a physicist, proves that this trace came from a special lightning strike that showed magnetic effects in the tree.
And not an unimportant point - he suspects that in the center of the picture was found crystalline carbon, which could only be formed due to huge fields and pressures.

Interesting information. Something in the spirit of Grebennikov smile.gif
You can, by the way, conduct some joint research (for example, to start getting bark, take pictures).

The person is engaged in science, has 2 patented inventions, and has investigated magnetic anomalies(see the end of the document)

And the bark itself is weak to photograph? M. b. This is a typical pattern of bark beetle moves...

what kind of lightning?! judging by the description, everything is typical. Any textbook on forest entomology will be full of such pictures.
