Dicyrtoma fusca, lateral, Netherlands Lateral 5:1 view of Dicyrtoma fusca. This species is characterized by its overall dark red/purple appearance. Furthermore, it is relatively large compared to other commonly found species such as Dicyrtomina ornata. I didn&#039;t measure this one, yet to a layman like me it seems about twice as large as Dicyrtomina ornata.<br /> <br /> In this scene, it is actually climbing over a Dicyrtomina ornata, the yellow species in the background. More information on how this was found and photographed in this post:<br /> <figure class="photo"><a href="https://www.jungledragon.com/image/104964/dicyrtoma_dorsosignata_heesch_netherlands.html" title="Dicyrtoma dorsosignata, Heesch, Netherlands"><img src="https://s3.amazonaws.com/media.jungledragon.com/images/2/104964_thumb.jpg?AWSAccessKeyId=05GMT0V3GWVNE7GGM1R2&Expires=1759968010&Signature=RNgLby%2BwIuJ3jzFO4dUxSOdKhcY%3D" width="200" height="134" alt="Dicyrtoma dorsosignata, Heesch, Netherlands Update: Matty Berg has confirmed this is indeed a new species report for the Netherlands.

A few days ago, I checked it again, and this time found 10 individuals.

From the earlier session 2 weeks ago I learned that handheld 5:1 photography is extremely difficult, as is obvious. So for this 2nd session I experimented a bit with a proper support system:<br /> https://ibb.co/YNg8RXN<br /> <br /> The metal frame in the bottom is not a tripod, it&#039;s a light stand, the Manfrotto 003. You can&#039;t adjust the height of it, it&#039;s just a super solid stand. Very heavy, and stays in place. It&#039;s shockingly inexpensive given the material and quality. Normally, you&#039;d put an extension pole into the stand, and then add lights or light shapers (umbrellas) to it. <br /> <br /> Not this time. I added the spigot (the golden-colored connector, Manfrotto 013) after which you can put anything to it that accepts a standard thread size. In this case, I added a super heavy duty tripod head, the Manfrotto MHXPRO-BHQ2. I normally avoid recommending gear in this place, but gladly make an exception for this jewel. This ballhead tripod head allows for a massive 10kg of load. And it takes it effortlessly. Even when under heavy load, you have fine grained control over movement and friction, in any direction. The ball is fully enclosed and therefore there is no grease. Given the class it competes in, this product is inexpensive and an absolute top performer.<br /> <br /> With this support system in place, most of my own movement is negated. Not to mention that it takes a lot of weight out of my hands, making possible a longer session. Focusing at the proper depth still is a challenge. My main method here is to use focus peaking via the live view screen. This paints a red overlay at the area in focus. Yet is tiny in this situation. I&#039;ve learned that the beginning of their antennae is the proper focal point. Combined with f/8, there&#039;s a reasonable chance the head is in focus. Still about only 1 in 8 shots are passable this way, so the strategy is to just shoot lots and hope for the best.<br /> <br /> The last challenge is light. With the end of the lens almost hitting the water, it&#039;s tricky to light the front of the animal. In this case I used the Godox AK-R11 Dome and positioned it to the side of the petri dish. I don&#039;t even own a Godox flash, this is just a cheap yet useful accessory. Next, I place a very strong flash unit in front of it. This effectively floods the scene with light that is strong yet spread. At 5:1 combined with f/8, the effective aperture is f/48. This means the Speedlight needs to fire at full power. Since no speedlight can sustain that for any length of time, I used a flash power pack.<br /> <br /> For now I have tentatively identified it as Dicyrtoma dorsosignata. I will update this post once experts have confirmed/rejected this proposal.
