Among certain beetle families or genera, particularly those that exhibit parasitic lifestyles, the first instar (the planidium ) is highly mobile to search out a host, while the following instars are more sedentary and remain on or within their host.
After the last instar, the mosquito larva becomes pupa.
The Union Agriculture Ministry’s Locust Warning Organisation then observed “low-density I & II instar gregarious/transient hoppers” at Jaisalmer and Suratgarh in Rajasthan and Fazilka in Punjab adjoining the Indo-Pakistan border.
At the end of each instar, the larvae molt, shedding their skins to allow for further growth.
Here they remain until they thrust through the cuticle and pupate (males) or release infective first- instar larvae onto flowers (females).
These first- instar larvae have stemmata (simple, single-lens eyes), and once they latch onto a host, they enter it by secreting enzymes that soften the cuticle, usually in the abdominal region of the host.
