I'm editing several interesting clips together, but wanted to share this one short clip right away. ;-)
Ebony Jewelwings have very sophisticated courtship and ovipositing rituals. Females line the stream banks to watch males "joust" for their attention. FEMALES pick their partner based on these competitions. That's rare in the dragon-damselfly world. Typically, the male literally grabs a female by the scruff of her neck and hope she cooperates! @@
The reason these jousting sessions are so important to the females is because the males "hover guard" the female they mated with, to ensure that HIS progeny's eggs are safely laid in the stream (they lay their eggs on partially submerged logs, twigs or leaves.) She depends on the male's ability to stand guard while she lays her eggs.
Ebony Jewelwings (Calopteryx maculata) prefer relatively clear, fast-moving streams. The male sentry butts heads and chases away any other male that tries to interfere while she's laying her (HIS) eggs underwater (their nymphs are aquatic). I got video of that behaviour too, but I'll save that for later.
This sneak preview is something I've never seen before. A rival male managed to slip past the hover-guarding male and tossed the egg-laying female right off her log!!
I always thought the competing male would just want to mate, but he seems to be more interested in interrupting the egg-laying process.
These beautiful and fascinating creatures never cease to amaze! ❤
