    Well, perhaps it’s not as much of a disaster as you imagine. 

    The “disaster” is affecting a lily flower. The black “turds” that you can see are the larvae of red lily beetles.

    Your dahlia is there, doing fine, it just hasn’t flowered yet. Probably feeling a bit crowded out by the lily plant.😊
    Apophthegm -  a big word for a small thought.

    I'm stumped. Is there more than one plant in there?  The foliage looks like dahlia but the flowers look more like lilies or something similar.  If they are, the black bits on the flower in the second photo could be lily beetle poo, possibly with larvae hiding in it.

    There's a Dahlia on the left - you can just see the foliage/buds. Get yer big specs on, Jenny  :D
    I'd remove all those flowers from the lily @Robert343, and any affected foliage too. The beetle larvae cover themselves with their poo, and it's easy to miss them. The beetles themselves are easy to spot, as pansyface indicates - bright red uppers. They can really devastate lilies. 
    Once your dahlia has finished, it's worth removing the lily and replanting somewhere else, giving it an additional bit of liquid food to boost it. Keep an eye on it though next year, and if you see any adult beetles in the meantime, remove and squish them.  :)

    Thankyou all for the useful comments Lily now removed and will await the delightful Dahlias. Will take care not to mix them in the future.

    They're both greedy plants in terms of food and water, Robert, so best kept separate so that you get the best from both of them  :)

    I said I could see dahlia foliage :D.  My varifocals cost a fortune so they better not be letting me down :)

    Those lily beetles are gits, they totally devoured one of my Lily’s 🙁. Now I wipe the leaves down with a tissue and remove their hidden lavae and squish them. Any beetles with the red jackets I get rid of too. You have to stay on top of it and do it daily. 😊

    Lilly beetle must be the culprit. Black poo and destroy the lilly plants.
