Lepidostoma hirtum

Systematic position Lepidostoma hirtum belongs to the order Trichoptera (caddisflies), family Lepidostomatidae. This insect undergoes complete metamorphosis and is primarily known for its aquatic larval stage, although it frequently interacts with riparian vegetation near agricultural zones.

Biology and life cycle Adult caddisflies are moth-like insects with hairy wings. Females deposit eggs near or into water sources. The larvae construct portable cases using organic material such as leaf fragments or sand, which provide protection while they forage for food along the water's edge.

Nature of damage Damage is caused primarily by the larval stage, which feeds on the foliage of plants growing in water or wet soil. This results in skeletonized leaves and irregular holes, which can weaken young plants and reduce their overall photosynthetic capacity during critical growth stages.

Host plants This species affects crops grown in river floodplains and marshy areas, as well as various ornamental aquatic plants. While not a primary field pest, localized infestations can cause economic concern for farmers working in proximity to ponds, streams, or irrigation channels.

Control measures Integrated pest management strategies include:

• Clearing bankside vegetation to reduce available nesting sites.
• Managing water flow to disrupt the larval development environment.
• Using targeted biological controls or Bacillus thuringiensis-based products when necessary.
• Regular monitoring of crop boundaries near water sources to detect early larval activity.
