>I read an interesting summary about a letter that appeared in Ecological 
>Letters 8, 290, 2005. It appears Monarchs injected with Protozoan parasites 
>show reduced flight performance and endurance in experimantal cages. It was 
>estimated this would increase the migration of a Monarch by about 9-10 
>weeks, thereby reducing the chance the butterfly will reach its 
>destination. This was speculated to account for the difference in parasite 
>burden between populations that migrate and those that do not, and that 
>habitat destruction and climate change will increase the prevalence of 
>parasites.
