Common Green Shieldbugs are (as the name suggests) quite common where I live. If you met a brand new one and an adult you’d be forgiven for thinking they were different kinds of bugs. They change a lot as they grow. They have multiple moults where they shed their exoskeleton to reveal the next stage that has developed underneath. They call the different stages instars, and Common Green Shieldbugs have 5 instars before they reach adulthood. They also have variation in colour between the ones that are mostly green and ones that have a lot more black.
As a biology nerd, I find lifecycles and such pretty fascinating and collecting images of the different stages is very satisfying 🙂
I don’t have any 1st instar photos of the bugs when they’ve just hatched, but I can show you the rest of their development.
Finally, here’s a direct comparison between then (2nd instar) and now (adult):
Inspired by the Lens-Artists Photo Challenge: Now and Then.
Note: While I am very much a biology nerd, I am not qualified to be absolutely sure of my instar identifications. Hopefully I have identified them correctly but don’t take my word for it!
