    Default What a grub!! Three inches long

    Okay, this was not on my orchid, but.. was on a trailing vine, this grows in a pot, I know this forum is for orchid growers, but can anybody tell me what this is. It decimated the vine, 3 inches long, and has what looks like eyes on top of his head. Quite weird.Name:  Grub.jpg

    Those look like what we called tomato worms...because I've always seen them on tomato plants. Could be a relative, but the horn on the backend looks very familiar. Not their real name obviously....maybe someone else will be able to help out.

    That I think would be the larvae of Hawk Moth! Rosie, instead of feeling/ showing concern about hijacking the orchid forum or posting inappropiate thread there is a forum sect/ room here where all of us can openly side track from subject of orchids to post and discuss anything not orchid related and off it goes. Sometimes our pets get a post or two.

    Thank you Matt, for the correct location of blogs on 'other things'. And I also think you are correct on the description of the worm. I remember vaguely this description of quite a large worm. Are they the giant span moths, one might see in the night garden? It was quite horrific, as I bent down to see what this grey fungus like thing was on the stem of the vine, as I touched it, it felt spongy and I screamed out, quite irky!!!

    Thank you Matt for that advice. Will heed in future. I think you are correct with the Hawk Moth, I recall this in a magazine once. The moth must be quite big.

    Hi Rosie, there are a fare few species of Hawk moth, your particular guest that gave you a suprize isnt the two popular photographed large winged span types. Atlas moth is huge. They are beauties though. You can purchase the larvae or cocoon of these species and more as an educational aid or simply an experience or study. The giant atlas moth is quite a popular choice for hobbyists and entomologists.

    Those eye patterns on the caterpilla scare off predators fooling them with the mimicery and deceit of being larger than it realistically appears. Moth larvae often feed on various plant sources often those deemed toxic and poisnous, an extraction tactic they use also as defence if the 'eye' patterns fail with perusing birds. Although Im sure the damage sustained by a bite attempt to realise the nasty taste is a risky one with ltd success. Mimicery and deceit are popular survival/ reproduction techniques as we well know with our fascination within the orchid world.

    If the idea of entomology appeals to you at all in anyway, its an interest that easily compares to the size of the orchid world. Silkworms/ moths are a great experience. Unfortunately these 'huge' subjects clash and collide in terms of practicality unless you have more than 24 hours in your day. I never surrender any time allocated to my orchid collection so juggle whats left with entomology and herpetology. How can anyone say theyre bored?

    Different species than what is found over here. Some of the hawk moths are also referred to as "hummingbird" moths for their ability to hover in place like a hummingbird whilst sipping nectar from a flower.
