Redgram pod trichomes are very important for giving considerable resistance to insects feeding on them. These pod trichomes were observed under foldscope.

Aspirgillus niger is a fungi, which causes diseases in plants. This fungi is cultured and made up slide. This slide is observed and studied through Foldscope.

A pterostigma is a group of specialized cells in the outer wings of insects, which are often thickened or coloured, and thus stand out from other cells. It is particularly noticeable in dragonflies but presents also in other insect groups, such as snakeflies, hymenopterans, and megalopterans.


 The pterostigma is a dark pigmented spot on the leading (front) edge of the wings of some species of insect. The spot is towards the wing tip and often stands out due to its coloration. Experiments have shown that the pterostigma, being heavier than surrounding areas of the wing, helps the insect when gliding. In particular, the pterostigma reduces vibrations within the wing. The pterostigma is present in the fore and hind wings of dragonflies and damselflies. Other insects have pterostigmas in their fore wings such as some Hymenoptera and Neuroptera.

 Scientific name: Myrmeleon sp. (Neuroptera: Myrmeleonidae)  Antlions have long clear wings with many veins and long delicate bodies. Some of them have dark markings or spots of color in the wings. Plumose hairs are scattered on the dorsal and ventral part of the body. Short, club-shaped bristles with a cut off tip, named dolichasters are present on the Antlion body surface. These are beneficiary insects which feed on crop insect pest like ants.

 Observed filiform antenna from insect antenna part under foldscope. It was curious to observe filiform antenna structure in detail using foldscope.
