Small Tortoiseshell caterpillars
Small Tortoiseshell caterpillars
Hello This is my first visit to a forum like this
we currently have a few hundred of these catapillars eating their way through the nettles in our garden.
If anyone could confirm the species I would be most greatful

Thanks

"Wild" gardens are always more interesting - for me anyway
Pupae are normally quite difficult to find, since the larvae will tend to wander off and find a secluded site somewhere nearby to pupate. Having said that, I have found Small Tortoiseshell pupae on nettles before now.
When the numbers start to decrease, this is probably because the fully-grown larvae are pupating. Although there is some concern that Small Tortoiseshell succumb to parasites and disease, which may be the reason for the worrying decline in this species. But this could be a good time to place a few larvae in an airtight container with fresh nettle in (change each day) and with some absorbent material in the bottom. You'll then get to see the larvae prepare for pupation, where they'll hang upside-down in a "J" shape, and pupate within a couple of days.
Just remember to place the pupae somewhere where the adult can emerge safely and inflate its wings.

We are doing it right now!!!
We have got a little fish tank which has holes at the top. It is suitable?
How many do you think we could put in it?
Should they be kept outside or inside the house?
There are a lot of different sizes and think they may be dead......lets hope the big ones keep munching!
We never knew we could have so much fun in our own wilderness.
Can't wait for the next installment of pictures.

The main reason for using an airtight container is to keep the foodplant fresh. Nettle, in particular, doesn't too very well when cut and an airtight container will reduce the time it takes to dry out and wilt.
If you have an airtight container that would be preferable, in my opinion. If you've not bred larvae through before, I'd also recommend that you keep the number small. Probably 5 on this first attempt.
You can keep the container indoors (it will probably speed up the development of the larvae since the temperature will be higher). Whatever you do, *never* put the container in direct sunlight, since the temperature will go through the roof, and kill everything in the container!
Yes - you may well have some larvae that have already succumbed to parasites or disease.

Oh no.....it is the only thing we could find.
We have clingfilmed the top which is the best thing we can think of at the moment.
We have only put four in it and they are now exploring their new home.
They are addictive to watch especially when they are feeding, they are just so cute.
Fingers crossed!
Sorry for asking so many questions but what type of air tight container would you suggests?

This is the latest picture of one of my family. It was hard to get a good picture because there is not much room in the tank for a camera....especially as it is full if nettles!!
Nearly all the ones in the garden have disappeared.
When would you guess they will start to pupate as we are going to have to go on a mission to find more nettles soon!
