To raise the Brown Hairstreak (Thecla betulae) has been a particular joy in 2015. After collecting eggs in the wild (see this post) I had the chance to see one of the caterpillars hatch from the egg while capturing the moment with my camera.
Place a decent twig of food plant in the cage and you’ll have a true meditation moment whenever you try to find the well hidden caterpillar on the bottom side of a leaf. Also the chrysalis can hardly be found. I definitely suggest this species to anyone who likes raising caterpillars that like to hide themselves.
