Spot the shag

[Larry Colen]

I went for a bike ride yesterday.  The best thing that can be said about this 
photo is that it has nothing to do with any of the chaos and strife going on. 
The second best thing is that it has a cormorant in it.

If that leaves you aching for a closer shot of a cormorant, there are a couple 
in this album

Re: PESO: Zinnia

[mike wilson]

Do you have Buddleia over there?
https://en.wikipedia.org/wiki/Buddleja
It can get a bit tall and rangy but rewards regular hacking back by becoming a 
bush dense with flowers that are attractive to all sorts of flying insects as 
well as people.

Re: PESO: Zinnia

[Daniel J. Matyola]

Yes;  here, they are commonly referred to as Butterfly Bushes, and they are
the primary attractor for all butterflies and for hummingbirds as well.  I
have several small bushes in my "Monarch Waystation," but a little more
than a year ago I lost my big bush, which was 15 feet high and almost as
wide.  I am not sure if it succumbed to old age, or disease, or
over-pruning by the crew that my wife hired to clean out some of our
overgrown shrubbery, but it was simply magnificent.  I am hoping that some
of my one and two year old replacements will fill in its function this
season.

Of course robber flies are 'preprogrammed' how they approach their target.

I can assure you that experience and instinct is more effective than math.
Once launched, however, the air-to-air missile did rely on

PESO: Zinnia

[Daniel J. Matyola]

As you folks know, I'm quite interested in butterflies, particularly
monarchs.  To attract them, I use a number of plants, like Butterfly
bushes, Echinacea, Joy-Pye Weed and Milkweed.  The best annuals for
attracting butterflies is the zinnia, especially red zinnia.  They are low
to the ground. colorful and hardy, and they  spread out quite a bit, so
they make an excellent addition to my patio garden.

RE: PESO: robber fly

[mike wilson]

A friend spent five years there recently, as part of a Darwin project, trying 
to undo three centuries of human abuse of the island.  Mainly removing flax 
plantations and recreating natural biomes on the hills.  I wanted to visit her 
but the cost (and potential unpleasantness) of the journey was rather 
offputting.

St Helena has an exceptional biological diversity.  Even so, to find a cuckoo 
wasp, which requires an extremely specific microhabitat to survive plus (being 
parasitoid) specific organisms to host their young, on an island in the middle 
of nowhere, is pretty special.

Thanks John. There are > 7000 species of robber flies in the world, some

They sting and paralyze their victims.
Their mathematic skills must be great, because I read they predict the 
traject of their preys in flight.

Since I once saw a robber fly attacking a damselfy I'm fascinated by these
killing machines.
There aren't many around that I can see, but today - a cold and wet day
- one was hiding on a leaf in the bushes.
Since this fly was not afraid of me I could get pretty close with the macro
lens.

RE: PESO: robber fly

Mike- at the last count I think there were over 500 endemic and unique
species living in the island.  Some have only been observed a couple of
times in the last 150 years, but recent sightings confirm their survival.
The planting of the Millennium Forest in 2000 has given many of them a
better chance to continue to survive.

St Helena has an exceptional biological diversity.  Even so, to find a
cuckoo wasp, which requires an extremely specific microhabitat to survive
plus (being parasitoid) specific organisms to host their young, on an island
in the middle of nowhere, is pretty special.
