Tipula spp. – Leatherjackets
Common name – Leatherjackets, daddy-longlegs, crane flies
Leatherjackets are unwanted pests that damage a lawn and can also kill or damage small plants in flower beds and vegetable plots by eating the roots and stem bases. They are often more numerous after a wet autumn or wet winter (They do not ten well in cold winters), as damp conditions favour survival of eggs and larvae.
Caused by larval stage of crane flies or daddy-longlegs
