Hope it never becomes an Olympic sport like synchronized swimming.
I have raised morning cloak butterflies in mass. They sometimes live colonialy as larva and I had hundreds one summer. The broods would emerge at the same time in any given cage. Wonder if they had a trigger like BMSB?
Ever see about 150 butterflies take wing at once?. My sons and friends loved it. Darwin and Mother nature both have it right. Nature has the edge.
In Annapolis area the BMSB has replaced our nearly indestructible native one. They are in turn being used as a food source for larva by a native Specid wasp. Mostly in the nymph stage. I have observed this and may have shots. I'll look. I find nothing on this observation, tho. Another project for this summer.
Night, all.
Night, Bob..

That is cool, but synchronized hatching is not unusual. Insects in egg masses of all sorts will do this, though I don't know what cues they use to do it.

Preying mantis.
It makes sense in the way a flock of birds makea sense. Odds of an individual falling prey are reduced.

Thanks for posting that, very interesting. I had noticed that stink bug eggs hatched at the same time.
