fleshy appendages along the abdomen, one pair on each

Hel 1 grammi tes are excellent bass bait and are 

 tenacious of life. The larvae may be kept in running 

 water or in a bucket of damp leaves. When kept for 

 more than a few days, they should be fed ground meat. 

 Because of cannibalism they cannot be crowded in holding 

 buckets. 



The larvae can be collected by placing a fine-mesh 

 net in the streams, turning over the stones immediately 

 upstream, and allowing the current to wash the insects 

 into the net. When used for bait, they can best be 

 carried in damp moss and it is advisable to hook them 

 through the skin at the middle of the back. 



Caddis fly larvae 



The larvae of caddis flies are found in fresh 

 water, both streams and ponds. The adults resemble 

 moths but differ in having hair instead of scales on 

 their wings and inlacking the long, curled-up proboscis 

 of moths. 



The larvae in the water resemble moth caterpillars 

 but are almost always characterized by possession of a 

 protective case which they fabricate from sand, bits of 

 leaves, or tiny twigs. Larvae of the larger species, 

 especially those normally occurring in slow streams or 

 along lake and pond shores, are much used as bait. As 

 many different species may beused, no accurate descrip- 

 tion can be given. All the bait species make tubular 

 cases. Many have threadlike gills along the sides of 

 the abdomen, and all have a pair of short, curved, 

 horny hooks at the end of the abdomen, apparently to 

 anchor them to their cases. All have six legs, with 

 which they drag their case-laden bodies over the bottom. 

 The species popular as bait are most numerous in beds 

 of vegetation, especially water cress and cattails. 



Most female caddis flies lay their eggs during 

 the summer, always under water and often in gelatinous 

 masses which may be affixed to submerged stones or 

 twisted around aquatic vegetation. The eggs hatch in 

 a few weeks, ?nd the larvae spend the winter feeding 

 and growing underwater. Generally the pupae are formed 

 in late winter and adults commence emerging in early 

 spring. Adults of a few species emerge on warm days 

 throughout the winter. 



Some of the larvae most popular as bait are highly 

 carnivorous andwill eat each other if confined together
