I’ve been tracking the growth of individuals in my Steatoda triangulosa colony, and finally have a whole 3 time points so I can estimate the spider growth rate. Behold, the first preliminary chart!
The line is a linear fit, which is not likely to be what I see in the end, but it’s optimistic, and I can’t really make many assumptions with so little data. But OK, if aiming to raise these spiders to a length of 1 meter, that’ll only take, with that assumption, about…a century? Yikes.
That rate is perfectly appropriate if they max out at 10mm long, like their mommy, but it’s going to be hard to take over the world with tiny little spiders like that. I guess I’ll have to go for numbers.
