After the hemolymph has been pumped, the wings need 2-3 hours to dry properly for flight. During this period, it is important for the monarch to remain hanging from the chrysalis. If their flight devices are frayed or torn, they are extremely difficult to repair.
However, this video from the Live Monarch Foundation demonstrates that wing reparation is possible with the right tools and a slow and steady surgeon's hand:
And how can you tell the difference between a male and female monarch butterfly? It's actually quite easy if you can get them to open up for a few seconds.
Males have a small dark spot on each of their hindwings.
Females appear slightly darker and have thicker wing veins.
In flight, the monarch's wings flap between 5-12 times a second. This is actually slow compared to other butterfly species, not to mention the hyper-winged hummingbird!
