Protocalliphora azurea

Friends, I posted the picture of this fly a few days back. You can view it HERE.
Today, I am going to show you its rear view :-).
Hope you like it.

As I submitted in the note with my previous post of this fly, the information on it on the web is basically of the technical nature.
However, I continued with my effort to gather more information about it and finally decided that the following abstract should be adequate in throwing some light on how the larvae of this fly affect the nesting birds. Here is the Abstract:

Detrimental effects of larval blow flies (Protocalliphora azurea) on nestlings and breeding success of Tree Sparrows (Passer montanus).
Author: Peter Puchala
Source: Canadian Journal of Zoology, Volume 82, Number 8, 1 August 2004, pp. 1285-1290(6)
Publisher: NRC Research Press

Abstract:

The effect of bloodsucking parasitic larvae of the blow fly Protocalliphora azurea (Fallén, 1817) (Diptera) on Tree Sparrow, Passer montanus (L., 1758), breeding success was studied in populations breeding in nest boxes in southwestern Slovakia. Out of 52 examined nests only seven broods (13%) were unparasitized. The mean number of larvae per parasitized nest was 22.6 and the total number of parasites per nest ranged from 1 to 80. Large numbers of blow fly larvae and pupae significantly influenced nestling survival and fledging success. In broods with parasite load per chick higher than nine, at least one nestling died. To record the effects of parasites on the body size of nestlings of different ages, nestlings were measured on days 5, 10, and 13 post hatch. First and second broods were analysed separately. A significant negative effect of parasite load per nestling on the body mass, wing length, tarsal length, and tail length of nestlings was found in the second broods only in the 10- and 13-day-old chicks. Tree Sparrow parents did not prolong nestling provisioning time per nestling, as there was no negative relationship between parasite load per nestling and feeding period. Contradictory to most previous studies of the genus Protocalliphora, the present study suggests that these parasites have an important negative impact on the breeding success of the studied Tree Sparrow populations.

Hello Ram,
Very unusual POV you presented us here :-)
I like the way the leaf is reflected in the fly chitin. Also, nice composition and colours. Very interesting abstract too.
Best greetings,
Michal

Bonjour,
Vue inhabituelle et originale.
Bonne journée.

Hello Ram,
The rear end of this Blow Fly forms part of a fine study in blues and greens, the fly's abdomen being the mixture of the BG blue and the green leaf. The result is a harmonious composition of colours with a little touch of red to add spice.
This is a pleasing composition to my eyes. However I wonder what the deep blue is: underexposed sky?
TFS and have a good week,
Ivan

hello mr thakur,

This is a much prettier beast seen up close than when it is buzzing around my dinner plate!
Fun image, with great colours and super composition
