Dissection needle prototype

Male moths have an aedeagus (equivalent to a penis) which in many species has 'armature' Here I have dissected out the spines of a single male Cabera erythemaria moth. Each would make a fine dissecting needle if I could figure out a way to mount them on a handle. Spines are chitin (a large, structur...

Re: Egg Papilio machaon update I & update II

I have several of this type of laundry basket with a finer weave, great for enclosing living plants + caterpillars; perhaps you could get one locally. https://www.ebay.com/itm/Laundry-Bag-Pop-Up-Mesh-Washing-Foldable-Laundry-Basket-Bag-Bin-Hamper-Storage/362971428063?_trkparms=ispr%3D1&hash=item5482...

Nikon's 10x finite (cf, Nikon CFI)

I feel somewhat of a Luddite here where many of you have switched to infinity optics. Constantly having to convince myself that I don't need to switch from my finites. So it is always nice to see a subject taken with an infinity lens that I can reasonably compare with a similar subject taken with my...

The probability of it surviving to an adult in the wild is about 1% - that's nature!

4/45 Apo-Componon Makro-Iris @ 2.77x

This lens reported as a very poor performer at 4x: https://www.closeuphotography.com/4x-lens-test-part-3 At 2.77x it performs well. Local back-garden ant Camponotus novaeboracensis D810, bellows, reversed lens at f/5.6, diffused flashes, Zerene PMax #1 full frame. 1st image (not used in the stack) #...

Re: 40/2.8 Apo-Componon @ 3.6x

Lou kindly sent an image of his species wing at the same mag. (3.6x) as mine taken with the Laowa 2.5-5x lens
I made a plate of a small section of each, Apo-Componon on left; each from a Zerene stack, not sharpened.
I can see no significant differences in resolution.

Re: 40/2.8 Apo-Componon @ 3.6x

M_C I read your blog RE: the Laowa, very informative. I was not impressed with the quality of the images shown on the Laowa web site for this lens. I don't have a Sunset Moth, or a chip. The moth wing photographed was from a common genus in Europe. I do have Vanessa cardui . Images are of the entire...

40/2.8 Apo-Componon @ 3.6x

In an earlier post: https://www.photomacrography.net/forum/viewforum.php?f=25 it was suggested that the Laowa 2.5-5x might serve me well in that magnification range. Currently I use the above Apo-Componon reversed on bellows on a FF Nikon (D810) I am wondering if anyone has an opinion as to whether ...

The lens is a fixed f/2.8, reversed on a Nikon bellows

Re: Dysdera crocata, the Woodlouse Spider

Interesting.
My text says they 'like' living with us - synanthropic (I had to look it up !).

Re: Nikon 2.5x M Plan vs. 40/2.8 Apo-Componon

Thanks everyone.
Amazing that JKT can spread such small moths. Too late for me to switch to Canon, too much invested in Nikon equipment.
I did manage to clean up the moth, re-shot it with the Apo-Componon, same setup as before, different lens:

Re: Egg Papilio machaon update I

Should be easy to rear to an adult if you place the egg on a living plant (of the same species) in a cage.
Cut off a small piece of stem containing the egg and attach the cut piece to the stem of the plant in a pot. The caterpillar will do the rest!
Best not to touch the egg or the young caterpillar

Re: Nikon 2.5x M Plan

Yes, a finite objective needing 210 mm tubing; NA 0.075; lens looks perfect. I reckon on a 'scope with a 10x eyepiece image will be good.
I have had this lens for a while, I now remember why I never use it.
I have a few enlarger lenses which give decent images at this mag., will reshoot the moth

Nikon 2.5x M Plan vs. 40/2.8 Apo-Componon

Would be a useful lens for this magnification but..... This small moth, L: 6.80 mm, is too large for my 4x objective which badly vignettes on the FF D810. Unfortunately the 2.5x is even worse than the 4x; and with less than a flat field. 1398.2 Coleophora deauratella , full frame and cropped (moth t...
