Please like my new YouTube #video, which shows interesting #interactions between #arthropods on a #dandelion #inflorescence:

It's about a #phoretic #mite that is persistently waiting on an inflorescence for a #transport opportunity. #Phoresy, also known as #phoresis, is a life-style strategy in which a smaller organism relies on being transported by a larger organism to #travel from one #habitat to the next. This strategy occurs in various #mitetaxa, including the #Mesostigmata, the Trombidiformes, the paraphyletic Oribatida, and the #Astigmata.
The mite featured in my video belongs to the Mesostigmata and extends the phoretic strategy by relying on leaving a host and essentially waiting at a #transferstation for a new opportunity to get on another host.
The dandelion inflorescence can be a #complexhabitat with astonishing #biodiversity. Arthropods such as insects are particularly common. Some species remain there permanently, feeding on the petals and reproducing there; others are only brief visitors seeking #nectar and pollen.
At the end of April 2025, I noticed that dandelions were predominantly #blooming in a dry #meadow in the Rehberge #urbanpark in #Berlin. The #moth #Pyrausta #despicata was often seen on the inflorescences, feeding on nectar.
I originally wanted to document this with video shots from many #closeup #perspectives. However, I was unexpectedly confronted with interactions between three different arthropods, which I documented in my video.
A mite of the #Parasitidae (Mesostigmata), possibly of the genus #Parasitellus, initially waited motionless at the edge of the inflorescence before seemingly launching an attack against the significantly larger moth. The moth reacted to the touch with a sudden, abrupt recoil.
What was the mite doing there and why did it attack the moth? The apparent attack was in reality the mite testing the moth to see if it could be a suitable carrier. With hair-like sensory organs on its legs, the mite quickly recognized that the moth was unsuitable as a carrier. This is because mites of the Parasitidae (Mesostigmata), in particular the genus Parasitellus, use the inflorescence as a transfer station from one carrier to the next. This strategy is called phoresy and was closer explained abive. Mites of the genus Parasitellus normally live in bumblebee nests. To spread from nest to nest, bumblebees are used as carriers. Since the same bumblebee will always fly to its own nest, the mite descends while its carrier visits a flower and waits there for a new carrier from another nest.
The moth needs to fear dangerous predators, as it is helplessly exposed while feeding on a flowerhead. For this reason the moth reacts with abrupt evasive maneuvers as soon as it feels touched by another animal. It makes no difference to it whether it is touched by a mite searching for its carrier or by the beetle Olibrus bicolor that accidentally comes too close. Numerous predators use flowers to overpower unsuspecting prey. These include, for example, free hunting crab spiders (Thomisidae) or hornets (Vespidae, Hymenoptera). But that's not all, the moth is also in danger when taking flight from the inflorescence, for example from the orb web of the #spider #Tetragnatha cf. extensa, which can be seen at the beginning of my video #documentation.
The authors J. M. Kolster et al. (2024) investigated the host range of mites of the genus Parasitellus that are associated with wild bees (Apiformes). They used DNA data from the mites, i.a.. to determine their #hostspecificity, which they found to be restricted to bumblebees of the genus #Bombus

A sunflower is a type of #inflorescence -- It is not a single flower, but a composite of many flowers!

#Plants deceive us!
#Dandelion is part of #Asteraceae family, which includes #daisies, #sunflowers, etc.
Each unit that appears to be a #flower, is an #inflorescence called #capitulum or #head, composed of many flowers (although sometimes it may have only one).

The second #Disa spotted on our Table Mountain hike was Disa ferruginea. #Endemic to Western Cape aka as the Cluster Disa. The beautiful red conical #inflorescence is unmistakable
