Could you collect some and find an old fish tank to keep them in for a day or 2.
You can keep them for longer and you don't need a fish tank...I kept some YEARS ago with older children. You need a container such as a jam jar that can hold water. Then you made a cardboard "lid" for the jar and put a hole in it to put the nettle stem through so the nettle keeps fresh but the ladybird doesn't drown if it falls off the nettle. Then you need something like an empty 5 litre water bottle (we used a sweet jar from a sweet shop, remember them?) If you use a water bottle you'll need to cut the neck off. Basically, you turn this upside down over the nettle in the jar, put in a few air holes-it stops the ladybird flying away. Then just provide a magnifying glass. Remember to change the nettles regularly and also the water in the jam jar.
You can also get a ladybird soft toy (IKEA have a couple in their "baby section") and have fun with rhymes like Ladybird Ladybird. Your toddler might also like "The Bad Tempered Ladybird" by Eric Carle...bound to be available at Smiths or from Amazon probably a lot cheaper or at your local library. If you have easy access to your library and can take the child to see if you can find any ladybird books that would be even better. You could also do some lovely dance and movement with a ladybird theme, crawling from leaf to leaf, curling up under something to shelter from a rain storm, flying round the room/garden etc. If you don't already have one, why not make a "home for ladybirds" by tieing some bamboo canes together to provide shelter then you should have ladybirds all through the summer!
