...the saddle and rider.
Taken using Olympus OM-1 with Zuiko f/1.4 50mm lens on Kodalith Ortho shot at 12 ASA and developed in a mix of Xtol(1:2) and Adonal(1:100) for 10 minutes to reduce contrast.
Stella and the locale deer share her space as they come close to man with the deep snow and lack of natural browse.

Plants are in a continuous battle with hemipterans (sap sucking bugs which have a long proboscis which they stick into the plant and through the plant’s own pressure they fill up the bug with the sugary phloem (sap).).This has led to an evolutionary arms race. It is not only the purloining of precious, hard earned sugars which is hard to accept for the plants, but these bugs also carry a variety of pathogens which can be transmitted to the plant via their unauthorized visitations. So the plants have developed a variety of defences, both physical and chemical. One such method is the introduction of small peptides into their sap which upon contact with air solidify, gumming up the mouthparts of any insect, and serving the dual function of forming a scab over the cut surface preventing further infection. This has stopped some insects though others have found a way around this. Chemical deterrence is another route that some plants have gone down. Toxic alkaloids or indigestible peptides laced with the sought after foodstuffs is a popular strategy. Though some insects have not only found a way around this, but have even exploited it to their advantage! Monarchs for instance feed on the toxic milkweed. Not only do they not suffer from the toxic alkaloids present in the plant, but they accumulate it and use it to in a similar way, so that they become unpalatable to avian predators. Together with their aposematic colouration, birds have learned to avoid them. Neotropical insects have developed along similar lines. To further complicate matters you have ants. These are both protectors and little Benedict Arnolds, selling out to the highest bidder – where the currency is sugar of course. When you can’t beat them, farm them! Plants have a love/hate relationship with ants. They have developed extrafloral nectaries for the purpose of luring ants to defend them from parasites and predators.This strategy is so effective that many species even those that are exclusively predatory, like trapjaw ants (Odontomachus sp.), can be seen patrolling the leaves of nectary producing plants. Plants that haven't developed extrafloral nectaries may also lure ants unintentionally since even leafbuds can sometimes produce sugary water through the ‘breathing’ of the stomata. But ants go where the sugar is, and so sometimes if a plant has become host to hemipterans, then ants will simply farm these invaders and reap the sugary benefits to the detriment of the plants. The complex interrelationships make for interesting study! Ants aren’t too picky about what they farm as long as they get the honeydew in return. Found during a night hike in Iwokrama rainforest reserve. For a greater selection of photos which include different angles and species ask by pm to be added to my friend's list.
Yesterday the tire flew off my minibus, I cut the head off a pit viper and I was banned from a commercial flight by associating with a narco-trafficker. Today I am bushwhacking through the jungle in the remote trail-less backwaters of Guyana, waist deep in water and praying to make it through the rest of the day alive. What will tomorrow bring? God only knows. The adventure starts here- pbertner.wordpress.com/.
