It happens that you flit through the meadow pollinating flowers, and suddenly one of them bites you!!!
Bad situation if you're a moth and a Crab Spider catches you))
So here, the drama broke out in front of me right on this flower...
It’s not difficult to guess why these spiders got their name)
These spiders are sometimes called banana spiders because of their striking yellow color. It is often very hard even for a searching human to recognize one of these spiders on a yellow flower.
The process of masking them is very interesting! Here's what Wikipedia said about it:
These spiders change color by secreting a liquid yellow pigment into the outer cell layer of the body. On a white base, this pigment is transported into lower layers, so that inner glands, filled with white guanine, become visible. The color similarity between the spider and the flower is well matched with a white flower, in particular the Chaerophyllum temulum, compared to a yellow flower based on the spectral reflectance functions. If the spider dwells longer on a white plant, the yellow pigment is often excreted. It will then take the spider much longer to change to yellow, because it will have to produce the yellow pigment first. The color change is induced by visual feedback; spiders with painted eyes were found to have lost this ability.
The color change from white to yellow takes between 10 and 25 days, the reverse about six days. The yellow pigments have been identified as kynurenine and 3-hydroxykynurenine
