Telepathy in mosquitos?

Around five in the afternoon here, mosquitoes become lively and start looking for their evening meal.  When I am sitting outside, perhaps with a drink, I become a target.

It may happen that I notice a mosquito landing on me and starting to feed (they don't waste time), and prepare to swat it.  About fifty per cent of my attempts to do this miss, no matter how fast I try to move.

But sometimes I am engrossed in reading, writing or playing freecell, or just doing nothing much, and don't notice a mosquito landing and starting to feed.  However, my body reacts automatically and my hand will move without any conscious intention on my part to scratch or rub the itch the mosquito is causing.  Even though my hand moves relatively slowly, it's surprising how often the offending mosquito gets squashed in this way, when my conscious attempt might well have failed.

Having read some of Cleve Backster's work on biocommunication, with plants and a polygraph,  it has occurred to me that perhaps the mosquito that I notice and prepare to swat has been forewarned by my conscious intention, whereas when I don't have any conscious intention to swat, it receives no such warning and moves too late.

I wonder if others have noticed this phenomenon and if so, what their explanation might be?
