Stag beetles fighting, video


This video is about two stag beetles fighting.

Everdien van der Bijl made this video in Laag-Soeren in Gelderland province in the Netherlands.

Scarce large blue butterflies, Dutch jubilee


This is a scarce large blue butterfly video from the Netherlands.

On 23 July 2015, there will be a celebration in the Moerputten nature reserve near Den Bosch city in Noord-Brabant province in the Netherlands. Then, it will be 25 years ago that scarce large blue butterflies, which had become extinct in the Netherlands, were reintroduced there.

Then, in 1990, 74 butterflies were freed. Meanwhile, there are hundreds. There are plans to introduce them to other nature reserves as well, as a species, limited to one area, is vulnerable to disasters.

In the Moerputten, the caterpillars are dependent, first on great burnet plants. Then, on Myrmica scabrinodis ants, when the caterpillars live as parasites in the anthills. They are also, indirectly, dependent on springtails: these are the main food of the ants.

Butterfly of the Month – July 2015

The Colonel (Pandita sinope sinope)

We have just edged past the halfway mark of the year 2015. A relatively quiet month so far, compared to the more tumultuous preceding months. The summer heat is upon us as Singapore‘s outdoor ambient temperatures move into the 30’s – and made worse by the high humidity. On my short business trip to Delhi and Ranchi in India at the end of last month, I experienced even higher temperatures, although fortunately, the monsoon rains have just started there.

ButterflyCircle members had an enjoyable weekend at the Festival of Biodiversity 2015 at the end of June. More forthcoming community projects with NParks are on the cards, with the NParks Butterfly Count project in September. A challenging project, considering that it involves the general community and sightings of butterfly species in urban parks have to be recorded and counted. Unlike birds, sighting and identifying butterflies requires a bit more experience and training. It will be a good platform to learn how best to deal with field surveys with beginners. …

Let’s leave the worldly woes for awhile as we introduce our Butterfly of the Month for July 2015 – the Colonel (Pandita sinope sinope). This Nymphalidae is one of many species in the family that has been christened with military names. In my article on this blog some time back, I gave some possible reasons how this came to be.

The Colonel is a mid-sized orange butterfly that may be considered moderately rare. However, it is quite local in distribution and often observed in the vicinity of its caterpillar host plants. Sporting an average wingspan of about 50mm, it is not an unusually large butterfly, and may be confused, when in flight, with several other orange-coloured butterflies.

The Colonel is a bright orange above, with the fore and hindwing bases shaded with brown streaks. The outer half of both the fore and hindwings is a prominent brown post-discal band and three dark submarginal lines. The underside is similarly marked, but lighter, with the basal wing area a greenish-grey.

The butterfly is skittish and active and flies with rapid beats of its wings and glides in a manner that is quite consistent with many related species in the sub-family Limenitidinae. Often it may be encountered at the ripened fruits of the Singapore Rhododendron (Melastoma malabathricum), on which it feeds greedily. In the early morning hours, it may be encountered gliding amongst the shrubbery and settling to sunbathe with its wings fully opened.

It is a forest butterfly, and rarely observed in urban parks and gardens. At times, it takes on a territorial behaviour, returning repeatedly to a few favourite perches after flying around to explore its environment. When feeding, it also tends to move its wings often and is very alert. Any threatening movement by an observer will quickly spook it off to the treetops.

The complete life history of the Colonel can be found on this blog article. The host plant on which the species has been successfully bred in Singapore is Uncaria. It has also been bred in Malaysia on another plant – Nauclea subdita also from the Rubiaceae family.

Beetles, flowers and green woodpecker


Ladybird, 10 July 2015

This is a photo of a ladybug on milk parsley flowers which are finished. I think this is an eleven-spot ladybird. It is from 10 July 2015, when we were in the Heempark again.

Near the entrance, a chiffchaff singing.

Young white storks, great crested grebes and dragonfly


This is a video from the Czech republic, about white storks with (still very young) chicks.

On 12 July 2015, to Warmond.

In the meadow, five white storks: the two parents and their three recently fledged youngsters. Later, they would fly back to the nest.

More to the north west, a white wagtail on a fence.

In the small pond in the nature reserve, a female black-tailed skimmer dragonfly, sitting on a reed stem. A blue-tailed damselfly flies past.

Many barn swallows flying over the meadow behind the woodland.
