A good friend Trish brought her bigger microscope for me to use.  It has a heavy base so the image does not move when I put my hand on the table.

Apple blossom looks as if it has a dark void in the centre, with red spikes around it.  Two huge stamens, no – pistils, with eight orange headed stamens in a central circle. As I moved it around I could see that the pistils sort of grow out of the leaf shapes at their base.

The other thing is that the pink colour in the petal disappears under the microscope.  Unlike the lichen which gets more colourful, the petals lose colour.    I wonder why?


After sketching a close-up of a buttercup, I researched insects and colour. Yellow is difficult for most insects to see as it has a wavelength of 580 nanometers.  Red is the lowest frequency, UV the highest.  Humans cannot see UV light directly.  Bees see red as black, and red light is invisible to moths.  Flies are attracted by blue and anything close to the level of ultra-violet light, but ultra violet repels them, as does green/yellow. Ultra violet makes patterns on flowers.I have some paint the shows up under UV light.  Maybe I could apply the paint to some cardboard flowers in the garden and see if what happens.
