Eventually I found out that the nest was on a larger tree nearby, but instead of flying directly to the nest as many other species would have done, these hornets were flying through the thick cluster of trees on their way back and forth!
The most common form in Singapore is slightly lighter, with a red or brown head and pronotum and some red and yellow markings on the abdomen, although I have also seen the completely black form. It seldom lands to feed on anything, except coconut flowers which are often at considerable heights.
This species is extremely variable in colour and pattern throughout its range. 946. However, unlike some hornet species in Southeast Asia, they do not scavenge on dead animals or food left behind by people. However, nests in the tropics reach substantial sizes. Vespa analis, known as the yellow-vented hornet is a species of common hornet found in Southeast Asia.
For more detailed information on this species and the giant hornet Vespa mandarinia in Hong Kong, you may refer to this paper I wrote and published under the Hong Kong Entomological Bulletin (published by the Hong Kong Entomological Society) Click here (link opens in new window). This species is generally considered to be one of the least defensive species. Record ID nmnhentomology_11121577 Usage of Metadata (Object Detail Text) CC0 GUID (Link to Original Record) In temperate areas, the nest gets only very slightly oval, and the colony size is generally not very large.

This species is one of the most widely distributed hornets.
Taxonavigation . The 20 V. analis colonies studied each contained a queen inseminated by a single male.
It can be found in temperate areas such as Japan, Russia and Korea, and is also found over much of China and Taiwan, down to tropical regions like Singapore and Indonesia. This was the most common colour form I found in Singapore. The three specimens below are, in respective order, typical Vespa analis from Southeast Asia, Vespa analis parallela from Russia and Vespa analis insularis from Japan.
Although the possibility of it belonging to Vespa affinis cannot be ruled out, it is more likely a nest of this species, due to the characteristic markings.
However, in Japan, it is responsible for quite a number of attacks, due to its abundance and its fondness for building near human habitation.
It can be found in temperate areas such as Japan, Russia and Korea, and is also found over much of China and Taiwan, down to tropical regions like Singapore and Indonesia. Their diet is relatively similar to other hornet species of Southeast Asia, catching butterflies, honeybees and dragonflies. I don't rule this possibility out, because almost everything about Vespa analis I have observed so far suggests shyness and a timid nature. The nest envelope is usually quite dark and sturdy, and has a coarsely imbricate pattern, with large, obvious overlapping circular sections. It appears to have a fairly long colony cycle and I have witnessed workers attempting to catch butterflies in early January, which indicates that some nests might still have brood or new queens then. Hornets (insects in the genus Vespa) are the largest of the eusocial wasps, and are similar in appearance to their close relatives yellowjackets.
The reason being that the wasps took a long detour through a thick cluster of ornamental trees, misleading me into searching for the nest among these trees! Vespa 946.
However, in Japan, it is responsible for quite a number of attacks, due to its abundance and its fondness for building near human habitation. However, I have not seen it scavenging on dead animals or food left behind by people, as Vespa affinis often does.

There are in fact two colour forms of Vespa analis in Hong Kong. From Wikispecies. Eliot Elisofon Photographic Archives, African Art, Assistant Secretary for Communications and External Affairs, http://n2t.net/ark:/65665/31385fb0a-2ccb-4b37-b6fd-46a0b34d2128. Apart from attempting to catch butterflies, I have observed workers in Singapore catching honeybees around flowers and chasing dragonflies, just as Vespa affinis often does.
A medium-sized to large hornet, worker specimens in my collection from various regions generally range between 20 and 30mm, although I have seen some truly enormous specimens in Singapore. Vespa analis, known as the Yellow-vented hornet is a species of common hornet found in Southeast Asia. In temperate areas, the nest gets only very slightly oval, and the colony size is generally not very large.
I have seen specimens in quite a wide range of locations in the New Territories and a few locations on Hong Kong Island.
The colony which took six weeks to track down is shown below; this is a typical nest of Vespa analis, already of quite a substantial size but still capable of getting bigger. Unlike Vespa affinis, which flies boldly around grass and forages everywhere in search of food, many of my sightings of Vespa analis were confined to it darting out from bushes or disappearing into them. , "Vespa analis" at http://www.vespa-bicolor.net/main/vespid/vespa-analis.htm accessed on the 11th October 2020, "Comparative functional venomics of social hornets Vespa crabro and Vespa analis", http://www.vespa-bicolor.net/main/vespid/vespa-analis.htm, https://en.wikipedia.org/w/index.php?title=Vespa_analis&oldid=983173442, Creative Commons Attribution-ShareAlike License, This page was last edited on 12 October 2020, at 17:50.

However, nests in the tropics reach substantial sizes. After observing it in the field for some time, I now realize the reason behind it being so elusive and thus causing me to erroneously consider it rare. Vespa analis is a typical tree-dwelling hornet.
, This species varies in colours and patterns, in Southeast Asia, they are usually black with a yellow marking on the tip of the abdomen (the sixth segment) In Singapore, they are coloured slightly lighter, with red or brown heads and pronotums. In areas where they occur together with Vespa mandarinia, they tend to resemble the colour form of Vespa mandarinia found in the same place.  In areas where they occur with the Asian giant hornet, they tend to resemble a similar colour and pattern to the Asian Giant Hornet. The nest envelope is usually quite dark and sturdy, and has a coarsely imbricate pattern, with large, obvious overlapping circular sections.  The nest envelope is usually quite dark and sturdy, and has a coarsely imbricate pattern, with large, obvious overlapping circular sections.
I have never seen a confirmed nest in Hong Kong, although I have seen photographs taken by hikers, deep in the countryside, built in small trees about six to ten feet (approximately two to three metres) off the ground, which appear to have been built by this species (all such photos were taken and shown to me when the colony had obviously died off).
The Vespa 946 is the purest and most modern expression of a style that for millions of travellers and fans is a byword for freedom and movement. This species is in fact very common in Singapore, but I only managed to see individuals after quite a long, hard search. Southeast Asian specimens are usually mainly black with only the tip of the abdomen (the sixth segment) yellow. This image is in the public domain (free of copyright restrictions).
 Specimens from sub-tropical, mountainous or temperate areas have yellow heads. , This species appears to have a fairly long colony cycle, as workers have been spotted trying to hunt in early January, indicating that some nests still have brood or new queens then.
