I don't suppose it is possible to identify which leech it is by photo alone. This meal would surely keep the leech going for a long time.

Hi Dennis,

My best guess for the leech would be the horse leech (Haemopis sanguisuga). Leeches such as this are very common in this small lake. I have made a couple of iSpot obs. of what I believe are Haemopis sanguisuga at the same lake in the past:

It certainly would sustain the leech for a good while if other diners didnt help out, the caddis larvae and freshwater shrimp would lend a hand disposing of the remains.

Sorry Patrick, it appears to be a beetle related to the Swollen Thigh Beetle or Thick-legged Flower Beetle (linked below), but I'm afraid I can't help with an English name.

Thank you Cathal,

Now that I know that it is a Horse Leech I shall be able to find out more about them. Knowing that it will not feed on me is reassuring! Nor on horses either, it seems.

Hi Dennis,

I should stress I think thats what they are but I am not completely sure about it. I wouldnt mind for someone else to confirm it first. I havent researched leeches much.

Rather than going paddling in the pond to find out if it may be a medicinal leech, could you re-post the photo under invertebrates? Perhaps somebody can give a definite identification.

Leeches

I'm not a leech expert but it certainly looks like a horse leach to me with the two stripes along the sides. Medicinal leeches have fine markings along their backs. Horse leeches typically prey on amphibians despite their name.

Thanks Masked Marvel, Derek

Thanks Masked Marvel,

Derek has just brought my attention to this one with an agreement. If I could be sure about the ID of the leech I would make this into a species interaction.
