Many insects have developed natural disguise to protect them from shuttlecock and other predators . Larvae and other insects , particularly those that feed on coniferous trees , often take on the form , coloring or pattern ofpine needles .
Stick Insect (Phasmida)
Stick insects , or walking spliff , are commonly brown or green , and range in size of it from ½ to 21 inches long . Though the minute insects are often compared to twig , the green I deport a warm resemblance to pine acerate leaf , especially when they hold their legs near to their bodies .

Brimstone Moth Caterpillar (Opisthograptis Luteolata)
native sulphur moth caterpillars are usually brown , but sometimes take on a green food colouring . These larva can hit length of about 33 mm , and have a bump project from their sixth section . To coalesce in with a tree diagram ’s natural needles or twigs , native sulfur moth caterpillars can " abide " on a tree branch and run their bodies outwards .

Pine sawfly larvae are yellow green or dark fleeceable with disgraceful , tan or orange straits . They feed on pine tree in the Southwest , feeding on the outer tissues of pine needle . Adult pine sawflies lie their eggs inside of pine needles . The larvae tend to attack the same specific trees year after year , leading to slower tree growth or death .
Pine Butterfly Larva (Neophasia menapia)
Pine butterfly stroke larva are 2.5 centimeter prospicient , and colored green with clean stripe and light green heads . They are often obnubilate with pine sawfly larvae , as both insects feed on and resemble pine needles . Like pine sawfly larvae , they are consider pest , as they have contributed to defoliation in the Pacific Northwest .
Bugs That Strip Needles Off Of Pine Trees
Pine phonograph needle weevils ( Scythropus ) masticate notch along the distance of pine needles causing them to brown and fall off . To manipulate an infestation , edit away and put down affected limbs or do nothing and the job should resolve itself . The adult are 1/2 inch retentive or shorter , are dark in color , have two couple of wings and a wasp - like visual aspect . infestation are usually small and unawares - lived – between 2 and 5 year — but have the potency to spread over gravid areas causing serious defoliation that stunts growth and toss off trees . The male are snowy and females are yellowish ; they both have contraband wing markings . The cat of the flatware - spotted tiger moth ( Halsidota argentata ) strips the pine needles off of Douglas fir trees . As most infestations are gone within one or two years , you do n’t require to apply insecticide , but you could discharge predatory Tachinid fly .
