Baby Slugs

imageFor the past few days there were some white blobs on the side glass of the terrarium. I inspected them with my magnifier, but it didn’t look like anyone was home. Should I wipe the glass clean or leave it?

Mating Dance

slug slimePart 2:
Two slugs mean business. As we all know from watching David Attenborough, slugs are hermaphrodites. The trails on the glass, sides and even top of the terrarium, this morning give a clue that there might have been some elaborate mating dance going on last night–and some actually mating.

If these two did mate, there may be a clutch of up to 30 eggs and then…a new terrarium will be in order.

To see mating slugs check this out. Its not Attenborough, but its pretty amazing. I know we all feel sorry for the third slug.

To learn about weird slug behavior check out this Slate article on slugs.

Not Quite Gorillas in the Mist

slug trailsPart 1:

The terrarium has some recently discovered local residents. There have been interesting track patterns on the glass in the morning. The origin of these trails has been a mystery until recently. Approaching the terrarium at night with a light has revealed two kinds of glass artists. The common earthworm and a pale sickly looking slug.

The slug, who was eating a pretty ‘yet to be identified’ leafy plant, was offered some arugula. The arugula was untouched, and the leafy plant lost another leaf. The next night I added a piece of green leaf lettuce. That did the trick! not just one slug appeared to eat it, but two.
