PARTICIPIAL PHRASE. Present participles, verbals ending in-ing, and past participles, verbals that end in-ed (for regular verbs) or other forms (for irregular verbs), are combined with complements and modifiers and become part of important phrasal structures.Participial phrases always act as adjectives.ometimes part of the noun phrase is delayed until the end of the sentence so that that portion of the phrase (usually modifying phrases  participial or prepositional) can receive end weight or focus.
A close examination of leaves on the ground will likely show leaves with only a small portion of their stems (petiole). This leaf drop is caused by the feeding of maple petiole borers, Caulocampus acericaulis. Petiole borers are small insects called sawflies, which are non-stinging wasps. The sawfly is only about 1/6 of an inch long and emerges from the soil in the spring to mate and lay eggs near the base of the petiole of maple leaves.
The fruit may be scabbed, streaked or a silvery color. Citrus thrips are tiny orange or pale yellow insects that attack citrus as well as many other types of fruit trees. They mainly attack young leaves and juvenile fruit and feed on the tree s sap.ike most mites, the citrus red mite is an extremely tiny pest, only 1/50th of an inch long and red or purple in color. These mites infest leaves and fruit. Intense infestations during hot, dry weather can cause leaf drop. To control Citrus Bud Mites spray the tree with Bug Buster or Trounce.
