If you find slugs disgusting, I suspect this post won't change your mind. It's a short series of shots of the leopard slug (Limax maximus) mating. There's a longer sequence over on my main site for the really obsessive.
I have seen this in the garden a couple of times before, and it is one of the most unusual matings you are ever likely to encounter. The slug is 'hermaphroditic', that is each slug has both male and female reproductive systems. But in the strange world of the leopard slug it still takes two to tango (both are fertilized by the process). That's oddity number one. Number two is that they do all this while suspended by their version of a bungee rope. Third, their sexual organ emerges from behind their head. And fourth, the organ is prehensile, has flanges and is a luminescent pale blue in colour.
A few minutes in, and their reproductive organs are entwined
The end
Camera note: all shots were taken with the Sigma 105mm F2.8 EX DG macro lens, except the first when I still had the EF70-300mm 4.5-5.6 DO IS on the camera.

26 Jul 2009Thanks! Very interesting. Slimy little buggers that they are. But I guess buggers isn't the right term! Well, maybe sort of!

27 Jul 2009Robin, slimy and strange for sure. Not sure about the terminology… maybe 'having their cake and eating it', which is (apparently) what they do if they can't untangle themselves :yikes: (Really!)

27 Jul 2009Mark, you have a thing about slugs, squishing and squashing them! Generally not the most interesting creature in the garden, but now and then they excel themselves.

27 Jul 2009Neil, they seem to like that wall, which comes down from a raised bed (sort of), so nice and handy for them. I was completely baffled the first time I saw it.

I was fascinated when I "caught" a couple of slugs in the act in my garden tonite. I thought that they were doing their thing but wasn't sure what the translucent blue blob was–now I know:)

30 Jul 2009Katy, glad the pictures were of use. I was also bemused by the blue blob the first time I saw this happening.

I just watched this last night. They were attached to a retaining wall on the side of my drive way. Creeped out my stepdaughter. We thought they were giving birth at first. I got the camcorder out and started filming. Got a little Paris Hilton action going when I turned the night vision on because i though I could get a better picture of it. I was expecting something more like aliens to happen. It was not until late last night/this morning I learned they were mating. It was truly an odd event. Lasted about 5 minutes.

Just saw this happen on my back porch… Weird but couldn't look away… And was confused! I thought they were going to give birth to some alien who was going to take my head off. But just turns out that they were getting it on!
Not gonna lie… Kinda feel like a creeper! Haha

15 Aug 2011Megan, it's a fascinating display. I've seen it twice over the years.

13 Sep 2011Be careful what you wish for. If they can't untangle one of them has its appendage bitten off!

18 Sep 2012Glad to be able to explain it. Leopard slug mating is certainly one of the oddest sights you are ever likely to witness in your garden.
