What is this larvae?



please help, I have bought some plug plants which I started to make up a hanging basket and I found some yucky grub things. Any that I have found I have crushed but I seem to be infested. 

I potted the plug plants on in new compost and I am unsure what to do and how to prevent them coming back.

i have tonight sprayed them, but am wondering whether to take all plugs out, getting rid of compost and to start planting them up again. Any suggestions please.

    If you bought them infested with anything you should take them back.

    I don't know what that one is, sorry.

    What did you spray it with?

    Nothing on the plug plants that I could see, the plugs were very small. Sprayed them with something that looked like it killed pretty much anything, beetles, caterpillars, weevils, aphids etc but not sure that it is the correct thing!

    I don't know, I don't recall ever seeing those - I'm just wondering whether they're larvae of New Zealand Flatworms - I've never seen those either but googling brings up some similar looking creatures.  

    As Nut says - take the plants back.

    Is it in a bag of old compost you have had or did they come in the plug plants?

    is there a mouth sucker on the underside? they look almost like leeches, but they are usually inhabitants of dank water like ditches.

    No bag of old compost I used fresh compost on all of them. 

    There is no sucker on the underside, they are more like a small fat worm.  They are getting everywhere. In lupins, lavender, bedding lobelia, calibrachea. Not sure what to do, I don't want to repot them all for them to just return again.

    As a retailer myself, getting a refund could prove tricky as you have potted the product on and sprayed it. However, as a consumer you have certain rights one of which is that the product 'did not do as it said on the tin' and , more to the point, was contaminated. I would simply bag up all the pots , go back to the retailer with your receipt of purchase, and show them the contaminated goods. Any garden centre worth their salt would offer you a refund, or, give you vouchers of a value equivalent to that of your product, to spend in the store. Most stores and garden websites have a Sale or Return policy of some sort.

    Where did you get the plants from?

    I've never seen NZ flatworms either, but i agree with dove, they do look a lot like the google images of them.

    Thank you Bruce Robinson, would you say they were on plugs or in compost though?

    mike Allen, I agree they look like cutworms, what do you think is best to do?

    But look like daddy long legs larvae too, we did have a lot of those about last year. Could that be a possibility too?

    Look more like leatherjackets, the photo is not very clear.  Either way a baddy.
