There is nothing to be compared with people gathering and having a wonderful meal together just like a occasions like birthday and others.
May the Good Lord grant you relief from any mosquitoes, black flies, noseeums and bears on all your picnics!
Well, that depends on the environment the picnic is scheduled to take place, though flies will always do there job but they had no parent and have to eat lol .
Do you feel the same about mosquitos (that they have to eat)? If so, better your blood than mine :-)
They feed on human just like we feed on plant and some animals. Though, I don't like being bite by giant mosquitos,lol. Because of chronic malaria.
