Mainland Rusty-spotted Cat (Prionailurus rubiginosus ssp. rubiginosus)

Date

March 2022

Description

I was attracted to the ruckus made by crows from a tree, about 200 m. from where I stood. Expecting them to be mobbing an unfortunate owl or bird of prey, I approached the tree, taking my time. The mobbing persisted.

When I finally reached the spot some ten minutes later I could see some 30+ House Crows cawing and flying around the target tree, which was a modest, barren tree with slender branches on which I first noticed the swinging of a bushy tail.

On approaching closer, I saw the small, fawn-coloured cat trying to get down from the tree but getting intimidated by the pestering crows that kept flying close or landing close to it on the tree, calling loudly all the while.

It was really unfortunate that these very circumstances that made this elusive animal uncomfortable opened up a rare window of opportunity for me to photograph it. For the next few minutes, I kept clicking as the crows prevented the cat from climbing down the tree and escape into the undergrowth.

As this drama was getting enacted, the poor animal seized opportunity to escape when a male Oriental Honey Buzzard flew in to land just 5 m. above my head on a young Eucalyptus tree. Momentarily, the crows got distracted with the unexpected arrival of this raptor that the cat was forgotten and the entire bunch landed seeking the buzzard's blood!

When I took my eyes off the honey buzzard and looked at the tree on which the harassed cat was stuck for the past several minutes, I was so happy to see it empty, the animal having used this diversion of attention of the crows away from itself to climb down and melt into the tangled undergrowth.

Though known to occur in lightly wooded rocky and scrub-covered areas, the Rusty-spotted Cat is rarely seen in the open and hence not often reported or photographed. I think it was one of those rare days and I was happy to be able to use the opportunity to photo-document this smallest wild cat.

Originally I had no idea what this was. I thought it was a cordyceps as it has erupted from the body of a katydid or grasshopper. Someone has suggested pin mold, another has suggested slime mold.
Found positioned on a decaying log in subtropical rainforest next to a creek. We have recently had lots of rain and high humidity.

Via a cordyceps identification page on Facebook, Nigel Hywel-Jones commented "It is indeed spectacular, and rare. In 35+ years and over 20,000 collections in 12 countries I have found it once. On an adult moth. That is how rare it is. It is in the genus Sporodiniella and is a Zygomycete. It looks similar to Sporodiniella umbellata."

So I have now listed it as such.

Description

This is a follow-up post to some odd growth on manzanita (Arctostaphylos manzanita ssp. manzanita) branches. Morgan Stickrod suggested that it might be a "disturbance response," which does occur in various types of Arctostaphylos. In this case, the disturbance seems to be woodborers. All of the burl-like growths on the outside of branches had woodbores underneath, inside the stem. However, this conclusion is based on a pretty small sample--I only opened up 3 or 4 sections of one small branch. (Manzanita wood was too hard for most of my available tools.) I found two types of woodborers; one I believe is Agrilus sp, possibly Agrilus arbuti which has been documented in manzanita in California. The second might be Lyctus sp, but there really isn't much to compare either borer to online, especially larvae or eggs. Photos 5-10 show the possible Agrilus bores, etc, and 11-12 are the possible Lyctus.
