Nymph - Unknown
Aug 21, 2019 19:41:58 #
This is a nymph stage of an insect that I do not know. It's about 2 millimeters in length and I had to rest it on a pin for it was too small to stick with an size #000 mounting pin as I typically do.
If anyone knows what species this is please share it with me.
I used a 50mm reverse mounted enlarger lens mounted on a 30 to 90 millimeter helicoid extension tube that I could extend or retract to bring the entire subject into view.
Thanks in advance to all those who view and for your comments, suggestions, questions and critique.

Oh Mark, I knew that I could count on you or Bill to come up with an ID. I will say that this must be one wild transformation to go from this spikey larva to a pretty round smooth spotted ladybug.
Mother Nature surely works in mysterious ways!

from the angle it looks like a Harlequin ladybird larva

These eat up all your aphids, I sometimes bring some home from the park for my garden.

I second Mark.
But I have another question.
What is the tube you use for focus? I find helical tubes on Ebay but not sure which is suitable. Seems like a bellows would work.

Bill, personally I think a bellows is a better choice and they expand further for more magnification.
My rig is not "bellows friendly" (older Nikon "F" model) because the Nikon D810 camera body protrudes past the lens flange so I have to add a short section of extension tube to get it to mount. The other issue I have is that the base rail of the bellows sticks out too far which interferes with the slide table that I use to adjust the mounted specimen in the four axis directions for fine tuning its position.

The detail is fantastic as well as the lighting but then that is your standard!

FYI, very sharp photo, not affected by the following: In the US, 'nymph' is usually reserved for insects with an incomplete metamorphosis (without a pupal stage, like grasshoppers, true bugs, dragonflies, silverfish, etc.), and 'larva' for insects with a complete metamorphosis (with a pupal stage, like beetles, butterflies, flies, etc. have.). But, in Europe (and other places), 'larva' applies to all. The former juves are usually similar to (unwinged) adults, the latter are usually more-or-less worm- or maggot-like, less so in many beetles, as yours shows, which can be confusing. Maybe the Old Worlders have a good thing -- all are 'larva', and some form pupae, and who cares!

Thanks for the very informative description of the differences. I truly know very little about insects other than that I enjoy photographing them at magnified views. To me each one is like a christmas present under the tree for I don't know know what it will turn out to look like and like that present, it's always a delight.

I’ve sat through an hour discussion on what dragonflies should be called in their life stage between egg and imago. Nymph, naiad or larva. This was among some of the top Odonatologists. They all had good arguments but did agree that it was different in different parts of the world. What ended the discussion was a participant who declared that we should just call them “babies.” Let’s go with that.

Doc, that is an excellent solution and one that I can easily relate to. At this point it is a picture of a little baby Ladybug.
