Leaf miner insect, La Isla Escondida, Colombia Moving back into my set to the morning, as I forgot to add this one. This looks like the work of a leafminer insect. My understanding of them is limited, but I've read there's both ant and fly species showing this feeding behavior during their larva stage.

Leaf miner insect, La Isla Escondida, Colombia

Moving back into my set to the morning, as I forgot to add this one. This looks like the work of a leafminer insect. My understanding of them is limited, but I've read there's both ant and fly species showing this feeding behavior during their larva stage.

  1. You don't know the plant, do you? Leaf miners can often be IDed based on the plant and the type of mine. Also, do you have any shots of the other side of the leaf? Some miners consume the entire parenchyma and thus the tunnels are visible on both sides of the leaf. But, other miners will only consume the top of the parenchyma and so the tunnels are only seen from the top of the leaf.The mines on this leaf are linear and end in a blotch, which means that the larva(e) basically made a straight trail. My guess would be that this was caused by an agromyzid fly (linear mines ending in a blotch with no distinct frass line). But, I could be wrong! Posted one year ago, modified one year ago
    1. Oh, and this shot is awesome! I love it! Posted one year ago
    2. Sorry, don't know the plant or have another angle, I really should have in hindsight! This album by Andreas shows a few examples in roughly the same region:

      He seems to call his examples caused by ants. Feels like a guess to me?

      1. I can't find where it says "ant" on his page...It does say "art"... Posted one year ago

  4. There are no leaf-mining ants. Leafminers are larvae of moths, flies, beetles, and sawflies. I only know North American leafminer species, but I would bet that this is a moth in the family Gracillariidae, genus Phyllocnistis (or something closely related). Agromyzid flies that make linear mines almost always deposit frass in a pattern than alternates from one side of the mine to the other; in these mines there is a faint, continuous central line. There is one North American Phyllocnistis species that makes a circular pupal chamber at the end of the mine like this (on plants in the avocado family). This genus is extremely diverse in Central and South America, with dozens (hundreds?) of undescribed species. If you were able to determine what this plant is you could check http://www.gracillariidae.net to see if any gracillariids are known to feed on it.

    (Sorry for the double post; I was just trying to clean up the HTML code once I realized it doesn't work here.)

    1. Thanks so much for the info Charley! By the way, Tracks & Sign of Insects and Other Invertebrates is my FAVORITE reference book and I have literally read it all the way through...But, I probably should have spent more time on the leaf-miner section ;). Posted one year ago
      1. Glad you like the book! I decided I should have spent more time on the leafminer section too, so now I've spent the past seven years focusing on them! Posted one year ago
        1. That's awesome! I know very little about them so far, but love finding them in addition to all insect sign. So much fun! Posted one year ago
        2. I, or perhaps better said we, love deep specialists. What fascinates you so much about leafminers, if I may ask? Posted one year ago
    2. Welcome to JungleDragon, and thank you so much for your input! Fascinating! Posted one year ago
      1. Thank you! I get a Google alert whenever anyone mentions leafminers on the internet, and when I saw these dazzling mines I couldn't resist chiming in! Posted one year ago
        1. We have a list here that includes a lot of insect sign (and other wildlife as well). Here's the link in case you're interested in checking it out:

    3. Thanks for chipping in! The mistake is mine, I misread "ant" where it was saying "art".
      Still, it got you here :)
