Coloured Scanning Electron Micrograph (SEM) of scales from the wing of a peacock butterfly, Inachis io. These scales have an intricate design and overlap like the tiles on the roof of a building. They allow heat and light to enter, and also insulate the insect. They may also be highly coloured. The metallic appearance of the scales is due to ridges along their length.
When you think of dinosaurs, you might think of those found in the movie Jurassic Park, but there were many other prehistoric animals that are still around today. And some lived even before dinosaurs first appeared: dragonflies and damselflies!
Damselflies (suborder Zygoptera) are insects in the order Odonata. Damselflies are similar to dragonflies, but the adults can be distinguished by the fact that the wings of most damselflies are held along, and parallel to, the body when at rest. Furthermore, the hindwing of the damselfly is essentially similar to the forewing, while the hindwing of the dragonfly broadens near the base. Damselflies are also usually smaller than dragonflies and weaker fliers in comparison, and their eyes are separated.
Although, the Damselfly is talented enough to tuck their wings onto their back, they are not skilled enough to be able to walk. That’s right, this particular insect has no problem landing but they are incapable of walking due to the position of their legs.
Love this- very educational….and look at all their funny faces!!

This is not a tasty gummy sweet but a Jewel Caterpillar (family Dalceridae) found in Amazon Rainforest. They are covered with sticky goo-like, gellatinous tubercles that provides protection from its predator like ants until they metamorphosise into winged moths.
That ant colony belongs to an invasive species of fire ant (called Red Imported Fire Ants or RIFAs) which cause more harm to the local environment than good. Researchers are experimenting with extremely high temperatures as a means to dispose of invasive insect species and, just so you know, molten aluminum is VERY HOT.
Not saying this is the best way to do it, but these folks are doing a service for the local environment and they got a beautiful piece of art for their efforts.
It’s also good for Science because we get to see what the inside of a fire ant nest look like. That’s really cool.
