PARASITE ATTACKED CATERPILLAR

Location : Palode, Thiruvananthapuram, Kerala


MY OBSERVATIONS


08-11-2010 -  A mosquito-like fly sucking the body fluid of  the caterpillar
We can see the yellow stomach of the fly after sucking the body fluid.

Similarly some white eggs are also seen attached to the body and hairs
 of the caterpillar. That may be the eggs of the parasite.

The vulnerable status of the caterpillar may be due to this type of attack
